Detailed Description

Physical constants and tuning parameters used only by the moisture and cloud-physics code.

These constants were previously carried in Source/ERF_Constants.H, which is included (directly or transitively) by essentially every translation unit in ERF. None of them is referenced by the dycore, advection, diffusion, I/O or boundary-condition code, so they live here instead: the microphysics schemes, the superdroplet particle code, the material-property database, and the moisture utilities are the only consumers.

Source/Microphysics is unconditionally on the include path for both the GNU Make build (Exec/Make.ERF) and the CMake build (CMake/BuildERFExe.cmake), so any file in ERF may include this header.

Note on naming: several latent heats appear here under names inherited from the schemes they were ported from. lcond (2.501e6) comes with the SAM lineage, while lat_vap (2.5e6) comes with the CAM/WRF lineage used by WSM6/WDM6 and is numerically identical to L_v in ERF_Constants.H. Likewise lat_ice and lfus are the same number under two names. They are kept distinct for now so that this reorganization does not change any answers; consolidating them is a separate, answer-affecting change.
