Soundings for idealized simulations:
Description of input_sounding files:
The format is the same as that for the WRF Model.
One-line header containing: sfc pres (mb) sfc theta (K) sfc qv (g/kg) (Note1: here, "sfc" refers to near-surface atmospheric conditions. Technically, this should be z = 0, but in practice is obtained from the standard reporting height of 2 m AGL/ASL from observations) (Note2: land-surface temperature and/or sea-surface temperature (SST) are specified elsewhere: see tsk0 in namelist.input and/or tsk array in init_surface.F) Then, the following lines are: z (m) theta (K) qv (g/kg) u (m/s) v (m/s) (Note3: # of levels is arbitrary) Index: sfc = surface (technically z=0, but typically from 2 m AGL/ASL obs) z = height AGL/ASL pres = pressure theta = potential temperature qv = mixing ratio u = west-east component of velocity v = south-north component of velocity Note4: For final line of input_sounding file, z (m) must be greater than the model top (which is nz * dz when stretch_z=0, or ztop when stretch_z=1, etc)
