Hi, is there a matlab function to read .grib2 files (these are files similar to netcdf but Matlab nclibraries cant seem to be able to read them) thank you

Hi, I need to read .grib2 files fast. I m currently using a java toolbox (njvarget) to read them but it takes a lot of time as the files are many. Is there a way to read them faster (changing function or reformatting them?)? thank you

As of R2023b, you can read data from a GRIB file (.grb, .grib, .grib2) using the Mapping Toolbox readgeoraster function. You can also get information about a GRIB file by using the georasterinfo function. These functions were enhanced in R2024b to support GRIB files that use CCSDS compression.

Hi Thalia,

If you just want to read grb2 files. You may want to check out nctoolbox (https://github.com/nctoolbox/nctoolbox/).

You find some documentation here (https://github.com/nctoolbox/nctoolbox/wiki).

It is not explicitly fast. Although at least I did not make the experince that pygrib or the netCDF-Java API are significantly faster.

A word of warning: It does not work out of a Proxy network. Best of luck.
