This is cloud microphysics package for GFDL global cloud resolving model. The algorithms are originally derived from Lin et al. (1983) [65]. most of the key elements have been simplified/improved. This code at this stage bears little to no similarity to the original Lin MP in zetac. therefore, it is best to be called GFDL microphysics (GFDL MP) . More...
The module contains the GFDL cloud microphysics (Chen and Lin (2013) [13] ). The module is paired with GFDL MP Fast Physics, which performs the "fast" processes.
The subroutine executes the full GFDL cloud microphysics.
