This is cloud microphysics package for GFDL global cloud resolving model. The algorithms are originally derived from Lin et al. (1983) [119]. Most of the key elements have been simplified/improved. This code at this stage bears little to no similarity to the original Lin MP. Therefore, it is best to be called GFDL microphysics (GFDL MP) . More...

	GFDL Cloud MP modules

Functions/Subroutines
real function	gfdl_cloud_microphys_mod::acr3d (v1, v2, q1, q2, c, cac, rho)
	The function is an accretion function (Lin et al.(1983) [119] )

real function	gfdl_cloud_microphys_mod::smlt (tc, dqs, qsrho, psacw, psacr, c, rho, rhofac)
	Melting of snow function (Lin et al.(1983) [119]) note: psacw and psacr must be calc before smlt is called.

Detailed Description

The module contains the GFDL cloud microphysics (Chen and Lin (2013) [32] ). The module is paired with GFDL In-Core Fast Saturation Adjustment Module, which performs the "fast" processes.

The subroutine executes the full GFDL cloud microphysics.
