[katya_p]

Hi,
I am using WRF v3.8. All programs worked just fine till today. But now there some problem with ungrib. in log file correctly are read start and end date:
2022-12-13 12:44:05.376 --- *** Starting program ungrib.exe ***

But I cannot understand why is written "Reading Grib Edition 1".
file with date 2003-09-26 12:00:00 is in GRIB1, while the request files are in GRIB2

Here is the namelist.wps:

Thank you very much

Hi,
Can you attach one of your input data files so I can take a look at the data? If the file is too large to attach, and you don't have another method to share the file with us, take a look at the home page of this forum for instructions on sharing large data files. Please also attach the Vtable you're using. Thanks!

Hi,
I uploaded the requested files to Forum Uploads. The file name is FNL_Vtable.zip. I put 2 FNL files one for 2003 (grib1) and one for 2016 (grib2)
Thanks

Hi,
For your simulation, it looks like you're only interested in the 2016 data. Do you happen to still have the GRIBFILE* files for your 2003 case linked to your WPS directory? If so, you need to make sure you only have the 2016 data linked in.

Hi,
All FNL files were linked. Their number is 609 (with different dates for years 2003 to 2016). What is strange that nevertheless what date I put in namelist.wps ungrib tries to process files from 2003 and than stops without any error message. These files (for 2003) are the only one in grib1. So following your suggestion with little modification I moved files (these for 2003) from dir with FNL and ungrib processed the rest of the files correctly
So THANK YOU VERY MUCH for your help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
