Daily Time Series of Precipitation, Soil Moisture and Soil Temperature
 *Available for OK Mesonet stations, ARM/CART stations and Illinois stations
Comments
  • The volumetric soil moisture at one model layer is simply the total soil water content in that layer divided by the layer thickness, 100 mm and 300 mm respectively.
  • The Illinois stations have only soil moisture available. Since the observations are total water content at 11 layers from the surface down to 2 m (0-10,10-30, 30-50, 50-70, 70-90, 90-110, 110-130, 130-150, 150-170, 170-190, 190-200).
  • The observations at Illinois stations are vertically intergrated to match the model layers. For example, the second model layer (10-40 cm) is compared with values derived from observations at 10-30 cm and 30-50 cm, simply V(10-30)+V(30-50)*0.5.
  • Observations at ARM/CART SWATS stations are at 8 depths (5,15,25,35,60,85,125,175cm). To compare with the model, values at 5 cm is used as equivalent to model layer 1, averages of 15,25 and 35 cm are used as equivalent to model layer 2, averages of 60 and 85 cm are used as equivalent to model layer 3.
  • At most of the Oklahoma Mesonet stations, the precipitation from LDAS forcing agree well with the local observed precipitation.

    • Monthly Mean Diurnal Cycle of Heat Fluxes
    * Available at ARM/CART EBBR stations.
    Comments
  • EXP000_0.05 and EXP000_0.01 are two new reruns submitted by NOAH group to investigate the areodynamic resistance issue to improve the surface fluxes simulations.

    • Skin Temperature Scatterplots
    * Available at ARM/CART SIRS stations.
    THESE ARE INSTANTANEOUS VALUES AT EACH HOUR.
    Comments
  • AVSFT(grib # 138) from the model output is used here.
  • All three panels in one plot have the same sample size.
  • Once GOES or ARM/CART observations are missing, the respective values from model output are ignored.
  • By changing the aerodynamic resistance from 0.2 (EXP000 control run) to 0.05, there is about 2K drop in mid-day skin temperature.
