…n 2-meter temperature and 2-meter water vapor mixing ratio to the output_noahmp diagnostic pool. The variables t2mxy and q2mxy are computed in Noah-MP LSM as functions of the vegetation fraction, and the 2-meter temperatures and water vapor mixing ratios over vegetation and bare soil (t2mvxy and t2mbxy; q2mvxy and q2mbxy), but were not directly output as diagnostics.
…fied the call to
subroutine seaice_noah.
-> in ./physics_wrf/module_sf_noah_seaice_drv.F, subroutine seaice_noah includes the
optional variables noahres, potevp, and snopcx. these three variables are used in
the Noah LSM but not used in the Noah-MP LSM. separate calls to seaice_noah as a
function of the LSM option reflects this difference between Noah and Noah-MP in
subroutine driver_seaice.
-> in mpas_atmphys_driver.F, modified calls to allocate_seaice and deallocate_seaice
accordingly.
…t2m, and th2m when
running the Noah-MP land surface scheme:
-> added the module mpas_atmphys_sfc_diagnostics.F to compute q2,t2m,and th2m for the
Noah and Noah-MP land surface schemes, separately.
-> removed the computation of q2,t2m,and th2m for the Noah LSM in mpas_atmphys_driver_seaice.F.
-> in mpas_atmphys_driver.F, added the call to atmphys_sfc_diagnostics in subroutine
physics_driver.
-> corrected Makefile accordingly.

This PR corrects the calculation of the 2-meter diagnostics (T2M, TH2M, and Q2) when using the Noah-MP land surface scheme. While the computation of 2-meter diagnostics is the same for Noah and Noah-MP over oceans, it is different between the two land surface schemes over land. In Noah-MP, the 2-meter diagnostics are weighted as functions of their respective diagnostics over bare soil and over vegetation. The updated diagnostics for Noah and Noah-MP are now computed in the new file mpas_atmphys_sfc_diagnostics.F.
