This is cloud microphysics package for GFDL global cloud resolving model. The algorithms are originally derived from Lin et al. (1983) [120]. 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...

Melting of snow function (Lin et al.(1983) [120]) note: psacw and psacr must be calc before smlt is called. More... | |
The module contains the GFDL cloud microphysics (Chen and Lin (2013) [37] ). 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.
