TESTS CONDUCTED:
The code compiles successfully on NCAR's HPC (Derecho) using both intel and gfortran/gcc compilers. The test runs are also successful including that with activated MMF groundwater scheme, urban scheme, and different combinations of PBL, microphysics, and surface layer schemes. (tested by Cenlin He and Tzu-Shun Lin from NCAR)

RELEASE NOTE: Coupling with refactored Noah-MP v5.1.2.
