I am working with QGIS and I would like to rasterize mesh data (ERA5 monthly averaged data on temperature) from 1998 to 2018 in order to perform zonal statistics. However, given the huge number of files that I would generate, I was looking for a more efficient way to rasterize these mesh data than the manual rasterize function provided by QGIS.

  • I thought about that approach, my only concern was about the time-consuming task to fulfill manually the "time" section for each monthly file. Commented Feb 4, 2022 at 11:02

Assuming you have GRIB format data-files, you could extract the relevant info using the ecCodes tools

Then follow this guide to pull out CSV data


CSV "X,Y,Z" data can then (if needed) be converted to TIFF image data, which might be more useful, depending on what analysis tools you're using
