GRIB1 file for ERA dataset no longer available

[MickeyPU]

Hi everyone,

I used to download ERA input datasets in the GRIB1 filetype. These GRIB1 files, meant for the ERA dataset, were previously pre-processed using the ungrib.exe tool in WPS. However, the website (NCAR RDA Dataset ds633.0) now offers only customized downloads in the NetCDF filetype. Unfortunately, these NetCDF files cannot be effectively processed using ungrib.exe. I remember that the link to download data in the GRIB1 format was accessible a few months ago, but it seems to have disappeared now.

Has anyone else encountered a similar issue while attempting to utilize ERA data for driving the WRF model? I would greatly appreciate any suggestions or solutions that can be provided to address this challenge.

Hi,
You can reach out to the RDA support group to see if they can provide an explanation and suggestions for you. There are also other places to obtain ERA data. If you do a search in this forum, you'll probably find a link or two that can take you to the data. If you are unable to obtain any gribbed data, you can follow the steps to convert your data to intermediate file format (expected by metgrid).
