Because the current ECMWF online tools available for post-processing the data (area subsetting and regridding) do not use a mass conserving interpolation algorithm we advise against using area and grid keywords in GFAS requests. The recommended solution is to download the data at the provided resolution and perform interpolation separately.

See Brief request syntax to understand each keyword.
