Hi All,
I want to run a test case using ecmwf data for a particular day last year. Am still trying to fault find an anomaly in our gfs/wrf model stream.
I have managed to source ecmwf 0.125 degree run files so have the initialization and boundary files necessary.
Now I need to find out if the Lvtable/Vtables etc. for ECMWF reanalysis dataset available on the UEMS/WRF EMS website would also work for these operational data sets, and if not, if anyone has built up a system to use the 0.125 degree dataset and has working configuration files and perhaps also some knowledge to share on things I need to change to the stock EMS to create a run (I have not upgraded to the new UEMS yet).
Best regards,
Theo

I used Vtable that comes with original WPS distribution. I believe it is the same that comes with EMS, but if not, here it is:
Vtable.ECMWF
Vtable.ECMWF

Hi meteoadriatic,
Cheers thanks, I see it is the one in the tables folder in my current one just called ecmwf (not ecmwf sigma). Fantastic, will give it a go.
Best regards,
Theo

Hi all (and meteoadriatic!)
So I got heavily side tracked and am only now getting to attempting to run the test case using ecmwf 0.125 deg data. It is on the latest version of UEMS which I was forced to install.
However, I note that Robert has not included any ecmwf vtables or gribinfo files, so I copied those from an older version of EMS. But, it looks like ecmwf used some form of complex packing type 50002 and I get the following error message in prep_degrib-ecmwf.log file:
******** No complex unpacking of gridpoint data.
******** Option not yet available
Anyone come across this or found a way around or have a suggestion?
