I have tried many variants in the syntax and I got output nc file only with the following: +proj=geos +lon_0=0.000000 +lat_0=0 +h=35807.414063 +a=6378169 +b=6356583.8 +units=km One error msg was also remains: szabot@manicminer:~/gdal_knmi_test$ gdalwarp -of NetCDF -s_srs "+proj=geos +lon_0=0.000000 +lat_0=0 +h=35807.414063 +a=6378169 +b=6356583.8 +units=km" -t_srs EPSG:4326 -te 0 50 10 60 NETCDF:"SEVIR_OPER_R___MSGCPP__L2__20200713T081500_20200713T083000_0001.nc":cot TEST_MOD_COT_NL.nc ERROR 5: OSRCalcInvFlattening(): Wrong input values Creating output file that is 3125P x 3125L.
