Surface-analysis nudging

Any issues with the actual running of the WRF.

Surface-analysis nudging

Postby AlexFr » Wed May 09, 2012 11:59 am

Hello,

I run WRF with upper air nudging for a long time period. Since the input data has a few level in the PBL my results in this area are not as good as I expected.
I then tried to run WRF with surface-analysis nudging using the ECMWF surface re-analysis data.
After reading the user's guide and all related subjects on the forum, I didn't sort out the way to run OBSGRID in that particular case.

OBSGRID uses met_em* files and need additional little_r formatted observational data. In my case the data are re-analysis.
Does that mean I need to process all the re-analysis fields to obtain a file for each lat/lon couple and each time? Which means approximately 28125 files each month?

I am a bit confused.
Any hint would be useful.

AB.
