DESCRIPTION OF CHANGES:
This PR is to activate "tuning weights of MixEn" ( NOAA-EMC/GSI#541 ), "tuning cross-scale/variable/time covariances in SDL/VDL/TDL" ( NOAA-EMC/GSI#542 ), and "simultaneous radar reflectivity and conventional DA without side effects" ( NOAA-EMC/GSI#543 ). The following options are added. Here, "r_ensloccov4{scl,var,tim}" (real) was used instead of previous "i_ensloccov4{scl,var,tim}" (integer). In addition, the restriction forcing pure EnVar in assimilating radar reflectivity was removed.
TESTS CONDUCTED:
I checked that the following tests were as expectation on Orion.
DEPENDENCIES:
Following PRs should be merged to GSI used in this workflow
DOCUMENTATION:
TBD
ISSUE (optional):
This PR is related to MixEn and SDL/VDL/TDL options introduced in #451
