GlobToolbox

Export as NetCDF/CF

The GlobToolbox 2.0 extends the BEAM file menu by the entry "Export NetCDF/CF product", which allows to export products originating from the Glob*-projects as NetCDF/CF-files. Thus, they may be read by every software capable of reading NetCDF/CF-compliant files, which, of course, includes the GlobToolbox 2.0. An exemplary header of such a NetCDF/CF-compliant file is shown below.
