GFS Precipitation Type Diagnostics Module

If dominant precip type is requested (i.e., Zhao-Carr MP scheme), 4 more algorithms in calpreciptype() will be called. the tallies are then summed in calwxt_dominant(). For GFDL cloud MP scheme, determine convective rain/snow by surface temperature; and determine explicit rain/snow by rain/snow coming out directly from MP. More...

	Foure algorithms are called to calculate dominant precipitation type, and the tallies are sumed in calwxt_dominant(). More...
subroutine	calwxt (lm, lp1, t, q, pmid, pint, d608, rog, epsq, zint, iwx, twet)
	This subroutine computes precipitation type using a decision tree approach that uses variables such as integrated wet bulb temperatue below freezing and lowest layer temperature (Baldwin et al. 1994 [11]) More...
subroutine	calwxt_ramer (lm, lp1, t, q, pmid, rh, td, pint, ptyp)
	This subroutine is written and provided by Jim Ramer at NOAA/ESRL (Ramer (1993) [159]). More...
subroutine	calwxt_bourg (lm, lp1, rn, g, t, q, pmid, pint, zint, ptype)
	this routine computes precipitation type using a decision tree approach that uses the so-called "energy method" of Bourgouin(2000) [28]. More...
subroutine	calwxt_revised (lm, lp1, t, q, pmid, pint, d608, rog, epsq, zint, twet, iwx)
	This subroutine computes precipitation type using a decision tree approach that uses variables such as integrated wet bulb temperature below freezing and lowest layer temperature (Baldwin et al.1994 [11]). Since the original version of the algorithm has a high bias for freezing rain and sleet, the revised version is to balance that bias with a version more likely to predict snow. More...
subroutine	calwxt_dominant (nalg, rain, freezr, sleet, snow, domr, domzr, domip, doms)
	This subroutine takes the precipitation type solutions from different algorithms and sums them up to give a dominant type. More...
