Soil types FAO at 10 km resolution : fraction of sand and clay FAO Digital Soil Map of the World at resolution 10 km FAO soil database, reduced to 3 classes WHS (UKPP used IGBP) FAO data at 5’ by 5’ interpolated at the operational model resolution
Soil depths ECOCLIMAP database at 1km resolution Lookup table with ecotypes Constant depths (2.5 m for w and 14.58 m for T) Lookup tables with ecotypes Constant depth of 3 m Constant depth at 2.89 m
Land covers ECOCLIMAP resolution 1 km 255 ecotypes derived from NDVI classification and a set of 12 pure ecotypes. Lookup tables between pure ecotypes and "flux conserving" averages for mixed ecotypes GLC2000 and GLOBCOVER 2009; lookup tables between land use categories and model parameters Global 1km data GLCC and CORINE (HIRLAM) ECOCLIMAP (HARMONIE) IGBP 1km dataset
