Dear list, I'm working with large netCDF files from the UK Climate Projections portal ( https://www.metoffice.gov.uk/research/collaboration/ukcp). More in detail I'm reading with the ncdf4 library this <http://data.ceda.ac.uk/badc/ukcp18/data/land-rcm/eur/12km/rcp85/01/tas/mon/latest/> file. Once loaded O can easily handle it but it is a strange reference system as follow: rotated_latitude_longitude[] grid_mapping_name: rotated_latitude_longitude longitude_of_prime_meridian: 0 earth_radius: *6371229* grid_north_pole_latitude: 39.25 grid_north_pole_longitude: 198 north_pole_grid_longitude: 0 If I load the .nc file in QGIS I see that the SR is "+proj=longlat +a=6371229 +b=6371229 +no_defs" where the values associated to *a* and *b* variables are the earth radius. Even if QGIS can read it, the raw file isn't projected properly (it seems tha QGIS is not able to handle such projection). Finally, using the ncdf4+raster libraries, I can easily generate e raster image but then I'm not able to understand I could I re project this raster in WGS84 reference system. Any helps? Cheers
