This is a bug fix release. Following are fixes associated with this release.
Physics
- Correct the counter-gradient term for temperature equation at the first level in the KEPS scheme (bl_pbl_physics=17), which causes instabilities and large biases at the first model level over water surfaces. Details
- Make Minor changes to Thompson-MP to align with changes made in CCPP for use in UFS. Details
- Fix a bug related to FVEG scaling of canopy heat storage in Noah-MP canopy energy balance calculations. Details
- Fix problems in HAILCAST quilted processes/tiling and some incorrect SI/non-SI unit conversions. Details
- Fix a bug in building height specification in the LCZ urban parameter table. Details
- Fix an issue in the revised MM5 (sf_sfclay_physics=1) scheme, where the model could potentially encounter an infinite loop. In specific conditions floating point roundoff errors were preventing a convergence condition from ever being met. Details
Compiling
- Make configure script more portable. Details
- Fix the ADIOS2 init API to support ADIOS2 v2.9.0. Details
- Apply type-mismatch for gcc-10 to all gcc targets. Details
Miscellaneous
- Replace a few wrf_messages and wrf_error_fatal calls by macros defined at the top of modules for urban schemes so that the code maintains consistency with those in MPAS. Details
- Update references and remove obsolete contact information related to lightning options (lightning_option = 1 and 2). Details
- Add User-friendly fatal error messages if the optional CESM aerosol data files required for the MSKF cumulus/Morrison microphysics aerosol interaction option (aercu_opt = 1 or 2) are missing. Details
- Remove the file "test/em_real/namelist.input_default", which is more confusing than helpful for users. [Details] (b552930)
