COLOR CODE:
ORANGE - CONFLICT: This descriptor is associated with two or more mnemonics, depending upon the NCEP BUFR table.
PURPLE - For WMO Table B descriptors: This is awaiting validation by the WMO (last updated by the WMO 05/04/2011).
For local Table B descriptors: This will become active soon.
RED - Either: 1) This local Table B descriptor is being phased out because it is now defined as either a WMO Table B
descriptor or a different local Table B descriptor (this does not apply to local descriptors defined as Code or
Flag tables, these will always be retained); or 2) This local Table B descriptor is being phased out because it
was never actually used (it had only been proposed).
GREEN - This local Table B descriptor is being phased out because it is not, or will soon not be, found in any
NCEP BUFR tables. This does not apply to local descriptors defined as Code or Flag tables, these will
always be retained (unless the descriptor was never used).
BLUE - This WMO Table B descriptor currently has, or previously had, an incorrect attribute in NCEP BUFR tables.
GRAY - This local Table B descriptor is reserved for TDL which does not use the mnemonic-based NCEP BUFR library
interface.

Mongolia (ZM--)}
- For surface SHEF AFOS precip reports (BUFR type 000, subtype 011) and "other" surface SHEF reports (BUFR type 000,
subtype 010): Normally either a three character ID consisting of the alphabetic surface airways ID (call letters), or a five
character ID consisting of the NWS River Forecast Center site name {alphabetic characters one to three contain the name of the city
or region, alphabetic character four contains the first letter of the state in which the site is located, and numeric character five
contains the order of the state, alphabetically, based the first letter of the state (e.g., I3 is Indiana). Some sites contain a
report ID similar to the second case except a sixth alphabetic character C, G or D is added (reason unknown).
- For surface supplementary climatological data reports (BUFR type 000, subtype 012): A four alphabetic character ID,
constructed from the raw SCD bulletin. Currently only U.S. reports are available (character one is K).
- For surface marine restricted and non-restricted ship reports [TAC format - BUFR type 001, subtypes 001 and 013, resp.;
BUFR format - BUFR type 001, subtypes 101 and 113): An alphanumeric character ID, ranging from four to eight characters,
constructed from the ship call sign. Reports with missing ship call sign get report id and ship call sign set to SHIP. In the
BUFR format many reports consist of 5 numeric characters - wonder if these really are ships?
- For surface marine drifting buoy reports (TAC FM-18 format) (BUFR type 001, subtype 002) and surface marine fixed
(moored) buoy reports (TAC FM-13 format) (BUFR type 001, subtype 003): A five numeric character ID, constructed from the
buoy/platform identifier. The first two numbers represent the WMO region and subregion. The last three numbers represent the
unique buoy identifier for that WMO region and subregion.
- The normal convention for drifting buoys is that character 3 in ID is either 5, 6, 7, 8 or 9.
- The normal convention for moored buoys is that character 3 in ID is either 0, 1, 2, 3 or 4.
- For surface marine drifting buoy reports (BUFR format) (BUFR type 001, subtype 102) and surface marine fixed (moored)
buoy reports (BUFR format) (BUFR type 001, subtype 103): A seven numeric character ID, where like in the TAC feed, the first two
numbers represent the WMO region and subregion, but now the last five numbers represent the unique buoy identifier for that WMO
region and subregion. If characters 3 and 4 are 00, then the buoy replicates the same buoy in the TAC feed if characters 3 and 4
are stripped out of the ID.
- For surface marine buoy reports (SHEF format) (BUFR type 001, subtype 011), surface marine C-MAN platforms (SHEF format)
(BUFR type 001, subtype 010) and surface marine tide gauge reports (SHEF format) (BUFR type 001, subtype 012): Four alphabetic
characters followed by one numeric character. Alphabetic character four contains the first letter of the state in which the site
is located, and numeric character five contains the order of the state, alphabetically, based the first letter of the state (e.g.,
C1 is California). The first three characters represent a station location in the state.
- For surface marine C-MAN platform reports (C-MAN format) (BUFR type 001, subtype 004) and surface marine tide gauge
reports (C-MAN format) (BUFR type 001, subtype 008): Four alphabetic characters followed by one numeric character, constructed from
the stationary buoy platform identifier. Alphabetic character four contains the first letter of the state in which the site is
located, and numeric character five contains the order of the state, alphabetically, based the first letter of the state (e.g., C1
is California). The first three characters represent a station location in the state.
- For surface marine tide gauge reports (CREX format) (BUFR type 001, subtype 005): A five character ID, where alphabetic
characters one and two contain the U.S. state post office ID and numeric characters three through five contain an index count
unique to each state. The ID is read from the NCEP tide gauge dictionary.
- For USGS River/Stream reports (BUFR type 001, subtype 009): Up to 16 numeric characters (operator descriptors expand the
number of characters from the standard 8 to 16).
- For RVF River Forecast reports (SHEF format) (BUFR type 001, subtype 014): Unknown. These data may no longer exist.
- For surface marine sea-level pressure bogus reports (BUFR type 001, subtype 006): A five character ID, where character
one is P and numeric characters two through five contain a unique index count.
- For surface marine coast guard reports (BUFR type 001, subtype 007): A four character ID, where character one is K and
alphanumeric characters two through four are constructed from the raw bulletin.

- Specific reports in BUFR type 031, subtype 001 (TESAC code form):
- Reports from Argo and other profiling floats should have RPID values Q[1-7]9nnnnn. Eg: Q2901859
- Reports with identifiers Q99nnnnn should be from instruments attached to marine animals.
- Most reports with 5-digit numeric ids with are from moored buoys (but not all).
- Moored buoys should have ids with middle digit between 0 and 4 (eg 42023).
- Gliders should have id n89nn (eg, 48907).

- Most reports with ids containing four alphabetic characters followed by a single digit (eg, PKYF1) are C-MAN
or similar fixed coastal stations. An exception noticed looking at data for one month are reports with RPID
of WTDOn (eg, WTDO7). These appear to be CTD's from NOAA ship Oregon II whose call sign is WTDO, but none of
these obs have been observed making their way into the GDAS TESAC dump files, likely because they arrive too

The modernized NWS Cooperative Observer sites can provide different variables, and on different schedules, dependent both on the type of site
(Phase I or II) and on the processing done as part of reformatting the data sent over the various communications systems in use. Here are
the primary differences:
- Phase I sites only report a single temperature observation per hour, valid at minute 0.
- Phase II GOES/HADS sites only report once per hour, but the reports contain 5-minute observations from the last hour.

- Not checked
Note1: Set to 'A'. An altitude discrepancy is defined as duplicate manual AIREPs with similar times, latitudes, and longitudes,
but altitudes that differ by more than 1000 feet. If reports on either side of the pair are available and are
adequately close, an attempt is made to choose the duplicate that fits best with those reports. If neither report fits
well enough to be chosen or if neighboring report(s) are not available, both duplicate reports are rejected [character
(for NRLQMS) or replication (for NRLQM) 5 (pressure/altitude) is set to 'B'].
Note2: These include:
1) Bad Airbus re-encoded AIREP.
2) Aircraft id is 'XX999' (normally occurs only for manual AIREPs, indicates flight id was missing).
3) Report marked bad in the decoder (i.e, odd values for various parameters are detected in the decoding process), for
example:
MDCRS: A non-alphanumeric character is found in the flight id or tail number.
MDCRS: The temperature precision is other than 100, 50, 25, 10 or -99.
MDCRS: The data relay system is other than 3.
MDCRS: The position QC is other than 0.
MDCRS: The flight phase is other than 3, 5, 6, 7 or 9.
MDCRS: The wind instrument is other than 0, 4, 8 or 12.
MDCRS: The roll angle QC flag is other than 0, 1, 3 or 9.
MDCRS: The mixing ratio QC flag is other than 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 or -9.
MDCRS: The ACARS interpolation flag is other than 0, 1, 2, 3 or 9.
Set to 'B' if manual AIREP is a near-surface UAL report (altitude less than 5000 feet and temperature is missing). These
are actually erroneous reports from UAL Airbus A320/A319 aircraft that Tinker has incorrectly re-encoded into AIREP
format. In these reports, the altitude is divided by 10, temperature is missing, the values listed as wind speed are
actually wind direction, and it is not clear what is listed as wind direction.) Report is rejected.
Note3: Set to 'd' if the report is a manual AIREP location duplicate. Report is rejected.
Note4: This occurs if report is a close duplicate with the same aircraft id in which the temperatures differ by a large amount
and the winds are missing in this (the rejected) report. This seems to be some sort of systematic error associated
with manual AIREPs. The report with the missing winds is generally the one with the bad temperature.
Note5: This occurs in duplicate check if an encode error is detected. That is, the report is a close duplicate with the same
aircraft id in which either the temperatures differ by more than 2.05 K or the winds differ by more than 1.25
meters/sec or 10 degrees. (Close duplicates with the same aircraft id and with temperature differences less than
2.05 K are marked as near duplicates.)
Note6: Set to 'P' if an unrealistic airspeed is found [either airspeed > 525 meters/sec for all types and all time differences,
airspeed > 350 meters/sec for manual AIREPs and all time differences, airspeed > 350 meters/sec for all types and a
time difference greater than 10 minutes, or airspeed > 700 meters/sec for Concorde manual AIREPs, in this case
characters (for NRLQMS) or replications (for NRLQM) 3 (latitude) and 4 (longitude) are set to 'I']. Report is
rejected.
Note7: Set to 'r' if track doubles back on itself [characters (for NRLQMS) or replications (for NRLQM) 3 (latitude) and 4
(longitude) are both set to 'I']. Report is rejected.
Set to 'r' if the report is redundant, diagnosed as multiple reports on the ground or multiple reports with the same
altitude below 8000 feet, which occurs during descents. Report is rejected.
Note8: Set to 's' if only one or two reports are available from a flight, except for manual AIREP flights. Report is rejected.
Note9: Set to 'S' if more than half of the available reports for a flight (or tail number for non-manual AIREP flights) were
previously rejected. Report is rejected.
Note10: Set to 't'. A time discrepancy is defined as duplicate manual AIREPs with similar latitudes, longitudes, and altitudes,
but times that differ by more than 60 seconds. If the reports are within 30 minutes, the time is averaged in the
report that is retained [character (for NRLQMS) or replication (for NRLQM) 2 (time) is set to 'R'). If reports on
either side of the pair are available and are adequately close, an attempt is made to choose the duplicate that fits
best with those reports. If neither report fits well enough to be chosen or if neighboring report(s) are not
available, both duplicate reports are rejected [character (for NRLQMS) or replication (for NRLQM) 2 is set to 'B'].
Note11: Set to 'v' if the report is fails the "bounce" test [both vertical speeds > 6000 feet/minute and have opposite signs, in
this case character (for NRLQMS) or replication (for NRLQM) 5 (pressure/altitude) is set to 'I']. Report is rejected.
If pressure is computed from altitude [character (for NRLQMS) or replication (for NRLQM) 5 (pressure/altitude) is set
to 'R'] change character (for NRLQMS) or replication (for NRLQM) 5 to 'i'.
Note12: Set to 'V' if an unrealistic vertical speed is found [either > 10,000 feet/minute for any time difference, or > 6667
feet/minute for a time difference greater than 10 minutes, in this case character (for NRLQMS) or replication (for
NRLQM) 5 (pressure/altitude) is set to 'I']. Report is rejected. These flags are also used if an ascent
discontinuity is found, where both the vertical speed is > 5000 feet/minute and a descending segment are found in an
ascent (report is rejected). If pressure is computed from altitude [character (for NRLQMS) or replication (for NRLQM)
5 (pressure/altitude) is set to 'R'] change character (for NRLQMS) or replication (for NRLQM) 5 to 'i'.
Note13: Set to 'W'. A waypoint discrepancy is defined as duplicate manual AIREPs with similar times and altitudes but with
altitudes or longitudes differing by 0.5 degrees or more. If the two locations are within 115 km, the positions are
averaged together in the report that is retained [characters (for NRLQMS) or replications (for NRLQM) 3 (latitude)
and 4 (longitude) are set to 'R']. If reports on either side of the pair are available and are adequately close
(i.e., within 2500 km), a position is interpolated to the time of the duplicates. The report closest to the
interpolated position is retained; the other report is rejected [characters (for NRLQMS) or replications (for NRLQM)
3 and 4 are set to 'B']. If only one neighboring report is available and its time is within 90 minutes of the
duplicate pair, the distances between the neighboring report and each duplicate is computed. If one is less than 1500
km and the other is greater than 1500 km, the nearer one is retained and the farther one is rejected [characters (for
NRLQMS) or replications (for NRLQM) 3 and 4 are set to 'B']. If none of these methods is applicable, both duplicates
are rejected [characters (for NRLQMS) or replications (for NRLQM) 3 and 4 are set to 'B'].
Note14: Set to 'X' if track makes more than a 75 degree turn [characters (for NRLQMS) or replications (for NRLQM) 3 (latitude)
and 4 (longitude) are both set to 'I']. Report is rejected.
Set to 'X' if altitude is an isolated maximum/minimum [character (for NRLQMS) or replication (for NRLQM) 5 (pressure/
altitude) is set to 'I']. Report is rejected.
Note15: Set to '2' if the rejected reports form a second flight (do not reject report).
Note16: In the eighth character (for NRLQMS) or replication (for NRLQM) (wind speed):
Set to 'A' if near-surface wind speed is too high (seen at ends of UPS descents) (reject only wind).
Note17: If both the temperature and winds are bad, stuck, or missing, reject the whole report (flags are set individually for
each quantity).
Note18: In the second character (for NRLQMS) or replication (for NRLQM) (time):
Set to 'B' if suspect time is rejected. Report is rejected.
Set to 'B' if overall report is deemed bad due to time discrepancy. Report is rejected.
In the third character (for NRLQMS) or replication (for NRLQM) (latitude):
Set to 'B' if the latitude is greater than 90 or less than -90 degrees. Report is rejected.
Set to 'B' if suspect latitude is rejected. Report is rejected.
Set to 'B' if an airspeed violation is associated with a latitude of zero. Report is rejected.
Set to 'B' if overall report is deemed bad due to waypoint discrepancy. Report is rejected.
In the fourth character (for NRLQMS) or replication (for NRLQM) (longitude):
Set to 'B' if the longitude is greater than 360 or less than 0 degrees. Report is rejected.
Set to 'B' if suspect longitude is rejected. Report is rejected.
Set to 'B' if an airspeed violation is associated with a longitude of zero. Report is rejected.
Set to 'B' if overall report is deemed bad due to waypoint discrepancy. Report is rejected.
In the third (latitude) and fourth (longitude) characters (for NRLQMS) or replications (for NRLQM):
Set both to 'B' if latitude and longitude are both zero (reject report).
In the fifth character (for NRLQMS) or replication (for NRLQM) (pressure/altitude):
Set to 'B' if pressure is too small (< 116 mb) or altitude is too high (> or = 50,000') (except for AFR and BAW manual
AIREPs above 50,000' which are are valid and allowed]. Report is rejected.
Set to 'B' if the pressure altitude is low (< 600 feet) and the report is an AIREP or manual AIREP (the AIREP format
does not allow negatives, so AMDAR reports with negative altitudes are re-encoded as AIREPs with a positive
altitude!). Report is rejected.
Set to 'B' if the pressure is greater than 1080 mb or less than 50 mb. Report is rejected.
Set to 'B' if the pressure/altitude on the ground is invalid. These reports are from United Airlines, which uses 2000
feet as its lowest report. They are detected as being within 5 minutes of a report at 2000 feet, with a temperature
greater than that in the 2000 foot report, and with an altitude difference greater than 6000 feet. Report is
rejected.
Set to 'B' if suspect altitude is rejected. Report is rejected.
Set to 'B' if overall manual AIREP report is a duplicate with an altitude discrepancy and is deemed bad. Report is
rejected.
In the sixth character (for NRLQMS) or replication (for NRLQM) (temperature):
Set to 'B' if a cold temperature with missing winds is found. This is a systematic error that is not always caught by
the gross check. The temperatures in this case are generally less than 200 K; a threshold of 205K is used in the
test. Report is rejected.
Set to 'B' if temperature fails the Moninger gross check. This often is a result of a bad altitude rather than a bad
temperature, so the entire report is rejected to play it safe.
In the seventh character (for NRLQMS) or replication (for NRLQM) (wind direction):
Set to 'B' if the wind direction is less than 0 or greater than 360 degrees (reject wind only).
In the eighth character (for NRLQMS) or replication (for NRLQM) (wind speed):

if in tenths (AIREP) (reject only temperature).
Note20: Relates to output from duplicate check.
In the sixth character (for NRLQMS) or replication (for NRLQM) (temperature):
A temperature encode error is detected. One report is completely rejected [value in first character (for NRLQMS) or
replication (for NRLQM) is set to 'E'] and the other (this) report has the temperature (only) marked bad with 'E'
(reject temperature only).
In the seventh character (for NRLQMS) or replication (for NRLQM) (wind direction):
A wind direction encode error is detected. One report is completely rejected [value in first character (for NRLQMS) or
replication (for NRLQM) is set to 'E'] and the other (this) report has the wind direction (only) marked bad with
'E' (reject wind only).
In the eighth (wind speed) character (for NRLQMS) or replication (for NRLQM):
A wind speed encode error is detected. One report is completely rejected [value in first character (for NRLQMS) or
replication (for NRLQM) is set to 'E'] and the other (this) report has the wind speed (only) marked bad with 'E'
(reject wind only).
Note21: In the second character (for NRLQMS) or replication (for NRLQM) (time):
Set to 'I' if the report is a UPS position report. These reports are performed every 5 minutes even during high-
resolution ascents and descents. The time on the position report is often out-of-sync with the time on the high-
resolution reports, so these reports are often out of order. Report is rejected.
In the third (latitude) and fourth (longitude) characters (for NRLQMS) or replications (for NRLQM):
Set to 'I' if overall report has an unrealistic airspeed. Report is rejected.
Set to 'I' if overall report track doubles back on itself. Report is rejected.
Set to 'I' if overall report track makes more than a 75 degree turn. Report is rejected.
In the fifth character (for NRLQMS) or replication (for NRLQM) (pressure/altitude):
Set to 'I' if the altitude computed from the pressure differs from reported altitude by more than 25 feet. Report is
rejected.
Set to 'I' if an anomalous point is found at the beginning of an ascent or the end of a descent. These points have a
higher/lower altitude than the following point in the ascent/descent and occur primarily in AMDAR/AIREP reports.
Report is rejected. If pressure is computed from altitude [character (for NRLQMS) or replication (for NRLQM) 5
(pressure/altitude) is set to 'R'] change character (for NRLQMS) or replication (for NRLQM) 5 to 'i'.
Set to 'I' if overall report has an unrealistic vertical wind speed or has an ascent discontinuity, or overall report
fails the "bounce" test. Report is rejected.
Set to 'I' if overall report altitude is an isolated maximum/minimum. Report is rejected.
In the sixth character (for NRLQMS) or replication (for NRLQM) (temperature):
If the temperature equals -9 degrees Celsius and would be rejected by the gross check, or three consecutive reports
from the same flight have a temperature of -9 degrees Celsius (or just two in a row at the beginning or end of a
flight), then reject the temperature (only).
In the seventh character (for NRLQMS) or replication (for NRLQM) (wind direction):
Set to 'I' if wind speed is missing but direction is not (reject wind only).
In the eighth character (for NRLQMS) or replication (for NRLQM) (wind speed):
Set to 'I' if wind direction is missing but speed is not (reject wind only).
Note22: In the second character (for NRLQMS) or replication (for NRLQM) (time):

constant time reports) and either 1) time equals zero; 2) altitudes vary less than 100 feet; or 3) altitudes
vary more than 9000 feet (to permit constant time for the bottom of a high-resolution sounding). Report is
rejected. (A flight must consist of three or more reports and the flight must consist of either of all manual AIREPs
or more than three automated reports.)
Set to 'K' if the report has a previously missed stuck clock. Report is rejected.

reports.)
In the fourth character (for NRLQMS) or replication (for NRLQM) (longitude):
Set to 'K' if longitude is constant within 0.005 degrees for the whole flight (but the longitude is not rounded to the

flight lasts more than 30 minutes. Report is rejected. (A flight must consist of four or more reports and the
flight must consist of either of all manual AIREPs or more than three automated reports.)
In the sixth character (for NRLQMS) or replication (for NRLQM) (temperature):
Set to 'K' if temperature is constant within 0.05 K for the whole flight and either the altitude varies by more than
1500 feet or the maximum altitude is greater than 25,000 feet (the entire report is rejected only if winds are
constant as well, otherwise reject only temperature). (A flight must consist of four or more reports and the
flight must consist of either of all manual AIREPs or more than three automated reports.)

AIREPs or more than three automated reports.)
Note23: A report is considered "empty" if the sixth (temperature), seventh (wind direction) and eighth (wind speed) characters
(for NRLQMS) or replications (for NRLQM) are all set to 'M' (means temperature and wind are either all missing or
all zeros). Such reports are rejected.
Note24: In the fifth character (for NRLQMS) or replication (for NRLQM) (pressure/altitude):
Set to 'M' only if both pressure and altitude are missing.
In the ninth character (for NRLQMS) or replication (for NRLQM) (mixing ratio):
