WEIGHT OF LIQUID AND ICE IN SHORT-WAVE SCHEME

[cibaouc]

Dear WRF community,

Thanks for your attention. I was confused about the weight of different hydrometer in line 375-376 in module_ra_sw.F

The detail code is below:
XLWP(K)=RO(K)*1000.*DZ(K)*(QC(K)+0.1*QI(K)+0.05* &
QR(K)+0.02*QS(K)+0.05*QG(K))

How to understand the weight coefficient of QC (which is 1), QI (which is 0.1), QR (which is 0.05), QS (which is 0.02) and QG (which is 0.05) ?

Are you questioning what these variables are? If so, they are as follows (descriptions can be found in Registry/Registry.EM_COMMON):

QC = cloud water mixing ratio
QI = ice mixing ratio
QR = rain water mixing ratio
QS = snow mixing ratio
QG = graupel mixing ratio
