Hi,I have been studying the observation nudging program (obsgrid.exe).
When I use met_em files at 3-hourly or 6-hourly intervals, I can successfully run obsgrid.exe and use the resulting OBS_DOM* files in wrf.exe.
In this case, the OBS_DOM files contain observation data at the same 3-hourly or 6-hourly intervals, even though the original observation data have a 10-minute time interval.
However, when I try to generate OBS_DOM files with a 10-minute interval (or any interval finer than the met_em interval of 3-hourly or 1-hourly), obsgrid.exe fails with the following error: "ERROR opening file: ./met_em.d03.*nc"
So my question is: is it possible to set the observation nudging (OBS_DOM) time interval finer than the metgrid (met_em) time interval?
In addition, if I generate the OBS_DOM files using other methods (e.g., Python, csh, etc.), will they be accepted and used correctly by wrf.exe?
