Hello! I’m currently trying to make ungrib files using ERA5 data and eventually want to make metgrid files. However, there are 2 types of ERA 5 data: pressure level data and surface level data. Can you enlighten me by answering the following questions? 1. We need to make GRIBFILE.* (e.g...

Hello I tried ungrib in WPS. As the picture shows, Vtable is unrecognized. What does the error "ERROR in Subroutine PARSE_TABLE" means? and How should I do next? Best regards.

Is there a way to configure the ungrib Vtable to read in only one layer of a 3D variable? We are working with multiple years and want to reduce input files to be 2D, if possible. Specifically, we are looking to just work with surface level MASSDEN, but currently we are running through all 50...

Hi all, I'm in the process of updating SSTs in the WRF v3.8 model but I'm running into WPS issues when attempting to convert GLSEA SST data from netcdf to grib. I'm aware that there are similar posts on this forum however, after trying out a couple of different options, I am still running into...
