Hi,
I am running WRF with the sst_update option and I would like to have non-zero sea surface currents UOCE and VOCE. As described below, I have tried to do this without success. I believe the problem is with the ungrib processing. Can someone help me?
WRF is reading UOCE and VOCE from wrflowinput_d01 and wrfinput_d01, but both files contains all zero values for UOCE and VOCE. The input files were created from 6-hourly NCEP Climate Forecast System Reanalysis (CFSR): ds093.0 (https://rda.ucar.edu/datasets/ds093.0). Following the directions in WPS/ungrib/Variable_Tables/Vtable.CFSR, I download 3d pressure files, pgbh06.gdas.yyyymmddhh.grb2 and surface flux files flxf06.gdas.yyyymmddhh.grb2 for my time period and processed then with ungrib.exe using Vtable.CFSR.
All the processing (ungrib.exe, metgrid.exe and real.exe) works fine with no errors, but with the end result that UOCE and VOCE are zero wrflowinput_d01 and wrfinput_d01. According to rd_intermediate.exe and g2print.exe there are indeed no sea surface currents in the either the ungrib intermediate output files or the input grib files.
There are also CFSR "ocean data" files ocnh06.gdas.yyyymmddhh.grb2 which according to g2print.exe contain the variables UOGRD and VOGRD. I tried to process these files but ungrid.exe fails ...
std error contains the message "Name of source model =>unknown model from NCEP GRID 4"
both std out and the ungrib.log file contain the message "unknown model from NCEP 98" and empty inventories.
I think that I need to add entries for UOCE and VOCE to Vtable.CFSR. The output from g2print.exe is supposed to be a guide for this, but I am at a loss for how to do it.
Any help would be greatly appreciated.
Best,
Steve
