The LSM_MOD.F script file at CMAQ_REPO/CCTM/src/depv/m3dry/LSM_MOD.F has this information about soil types:
The corresponding LSM_MOD.F code at CMAQ_REPO/CCTM/src/depv/stage/LSM_MOD.F has this information:
I am trying to understand how soil category properties are allocated in CMAQ, and have these questions:
Question 1a) Under m3dry deposition scheme, is CMAQ setting soil categories = 16 for WRFv4 and soil categories = 11 for WRFv3, irrespective of LSM used in WRF?
Question 1b) There are capitalized soil category property variables (e.g. WWLT_WRFV3(N_SOIL_TYPE_WRFV3), WWLT_WRFV4P(N_SOIL_TYPE_WRFV4P) ) and small letter counterparts (e.g. wwlt( : )). What/where is the latter used for in CMAQ?
Question 2) Under CMAQ stage dry deposition scheme, I am seeing 11 categories for WRFv3 with PX, 16 categories for WRFv4 with PX LSM, 19 categories of soil property for CLM and NOAH unaffected by WRF version. Am I understanding this correctly?
Question 3a) My MCIP files show 16 SLTYP values (I used WRF v3 with NOAH LSM, NLCD40 LU) which seems inconsistent with the 11 categories under m3dry as well as the 19 in stage model - what am I missing here?
Question 3b) There is a set of MCIP files in the CMAS repository (Output - Google Drive used PX LSM with NLCD in WRFv3) with 14 SLTYP categories. Again, 14 seems to be different from soil categories in both m3dry and stage models, and I cannot figure out why these MCIP soil categories are diffrent from those in CMAQ code?
