@guoqing-noaa I have finished adding 2m T/Q as background for surface observation DA. Now, we can use sensible temperature as background. |

…nsda_fix1 When running this regional_ensda branch for FV3-CAM tm06-coldstart hybrid DA, it was found the conversion subroutines like fv3_h_to_ll in "mod_fv3_lola.f90 was incorrectly used when the correct one should be , for example, fv3_h_to_ll_regular_grids in mod_fv3_lolgrid.f90. The incorrect use occurred in the subroutine called when fv3sar_bg_opt=1 ( on tm06 for tm06-coldstart exp for fv3-cam hybrid runs) and the newly merged gsi_fv3ncdf_write_fv3_dz subroutine. They should not have any impacts on HAFL's runs ( the problem would cause real time aborting rather than different results). Another change is to use crtm/2.3.1 from Mike Lueken to avoid GSI abortion when running on debug mode. The third ones are a couple of un-initialized variables in get_gefs_for_regional.f90. Li Bi already add those into the GSI EMC master. The changes in this branch is just to avoid getting those minor changes from that upstream master and confine the PR to between regional_ensda and regional_ensda_fix1. Contributor: TingLei-NOAA
