Issues with running 3DVAR.

T2, U10, V10, Q2 not updated

Postby rmcgrath » Fri Mar 08, 2019 4:36 pm

Running 3DVAR (version 4) assimilating conventional observations (SYNOP, SHIP,...). All seems OK but I notice that the output file (wrfvar_output) has identical T2,U10,V10, Q2 fields to the first-guess (fg) fields even though the statistics and gts_omb_oma_01 files indicate that the SYNOP values were used (AO values non zero). Other fields are changed (e.g. PSFC and upper-level fields). Any suggestions appreciated!

update_sfc_diags = .true.: update T2/Q2/U10/V10/TH2 with WRFDAre-diagnosed values.
Use only with sf_sfclay_physics=91 in WRF.
As the User Guide says, it could work when sf_sfclay_physics=91.
