Added Features of New Gridscale Cloud+Precip Scheme

• Extensive, computationally efficient lookup tables store calculations for rain and precipitation ice

• Smoother transition between upper-and lower tropospheric ice clouds by merging mass-diameter and fall speed-diameter relationships for ice

• Fall speed of rimed ice increases based on rime density (calculated), results stored in lookup tables

• Generalized form for microphysical equations, allows for stable calculations of rapid rates for large model time steps

• Assumes size of precipitation ice is primarily a function of temperature (Ryan et al., 1996)
