read_aic

Module:

File: ATM_DRV.f

Summary: read_AIC for a cold start, read the atmospheric IC file. Three input options are currently recognized (1) The input file has already been remapped to the model layering and contains the variables traditionally expected by the model (winds, temperature, specific humidity, surface pressure). (2) Winds, temperature, geopotential height, and RH are available on constant-pressure levels. Surface pressure is obtained via the hydrostatic assumption. Remapping from constant-pressure levels to the model layering is peformed, and RH is converted to specific humidity. The initial coding for this option was imported from init_cond/AIC.D771201.f and generalized considerably. If tropopause pressure and temperature are available, they are used in the vertical remapping. The coding for the assumed vertical structure of RH above the upper troposphere will be made more configurable as AIC files with better-quality RH data (than the historical AIC) become available. (3) Surface pressure, winds, temperature, humidity on "standard-hybrid" layers, where the pressure of the kth input layer at horizontal location i,j is equal to hyam(k) + hybm(k)*srfp(i,j) and srfp is the surface pressure. Remapping to model layering is performed. Condensate species are also (optionally) read on other branches, but not here (yet), for reasons including the inability of liquid and ice to coexist under the cloud microphysics on this branch. Logic will be added to handle other possible input layerings and combinations of available fields.
