Hi, While Bert is correct that there are plenty of tools, my preferred approach is to use the terra package to load a grib as a raster stack.
>From there, it's straightforward to use all the spatial tools with the data, or to extract it in whatever form and with whatever dimensions you wish. GIven the multidimensional nature of the data, "straightforward" may require some fiddling to get the format and variables you want in the way you want them.
