   • WebAPI CDS API (with ‘dataset’:'eac4'),  allowing users to download Global CAMS data in a programmatic way.
     
     
5. CAMS Global archived MACC Reanalysis, 2003-2012, approximately 80 km (T255 spectral) on 60 vertical levels from the surface up to 0.1 hPa for the analysed species) are available for download through:
