ungrib.exe -- "Data not found"

Having problems running the WRF Preprocessing Sysmte (WPS)?

ungrib.exe -- "Data not found"

Postby snoopy » Wed Dec 03, 2008 11:59 am

Hi guys, I am a new user of WRF.
After practicing the default case according to the online tutorial, I tried to use the data from GFDL to run WRF. However, I met some proble when running ungrib.exe.

My data is in grib1 format. One variable with a series times is in one file. Every variable has the same time series from 2000-01-16 to 2000-12-16 with one value in each month. I had 20 variables, so there were 20 files. When I was running ungrib.exe, the error information occurred:

Error opening GRIBFILE.AAU Error status: 2
INFORM: First pass done, doing a reprocess
Begin rrpr
Subroutine DATINT: Interpolating 3-d files to fill in any missing data...
Looking for data at time 2000-01-16_12
ERROR: Data not found: 2000-01-16_12:00:00.0000
FORTRAN STOP

Actually, my data is only from GRIBFILE.AAA to GRIBFILE.AAT; that is, I do not have GRIBFILE.AAU.
How can I solve it? Has anybody met with this problem before?
Looking forward your reply!
Thank you very much!

Are you using average data as input?
You should have use instantaneous data at a temporal resolution of 12h or higher for input.

I can use original NCEP NARR 3-hourly files to run, but time of downloading the data is too much. So I decide to use NCEP's NARR monthly means. However, it appeared the same problem "Data not found" when running ungrib.exe. I am not sure if NCEP's NARR monthly means can be used in WRF, or if the Vtable. NARR is not fit for NCEP's NARR monthly means? I am a new WRF user. Could you give me any advice?

Thank you.
