When trying to reproject S3 OLCI data, there seems to be a problem with the netcdf4-cf format.
Using SNAP and the reprojection module writes a netcdf file that is not recognised by gdal nor ncdump.
Using SNAP with graph builder that has a read, reproject and write module writes a netcdf that is ok.
Using GPT with the reprojection module does not work as S3 OLCI data is not a valid input format
Using GPT with a graph.xml that includes a read, reproject and write module writes a netcdf that is ok.
In the first case, the produced file can be opened in SNAP, so I guess it is a custom format (netcdf-beam?) that is actualy written instead of the netcdf4-cf.
It is not a blocking issue as there is already a workaround or am I doing something wrong?
We had now time to investigate this further. And honestly, I have no idea why it behaves differently.
One thing which could interfere with this problem is this issue: https://senbox.atlassian.net/browse/SNAP-1062
The output format automatically chosen is not deterministic if it is not specified.
