LUMIP is requesting subgrid output on four land-use tiles (primary_and_secondary_land, crops, pastures, and urban).
area_types for crops and pasture are already defined in the existing cf-conventions. New area_types required: *primary_and_secondary_land* - all primary and secondary vegetation that is not used as cropland or pastureland, should include forests, grasslands, bare ground and vegetated wetlands *urban* - urban settlements Additionally, the existing area_type pastures could include expanded definition *pastures* - Includes anthropogenically managed pastureland and rangeland Note that in our GMD LUMIP paper, we suggest that subgrid tile variables should be submitted according to the following structure, using Leaf Area Index (LAI) as an example: laiLut (lon, lat, time, landusetype4) – where the landusetype4 dimension has an explicit order of primary_and_secondary_land, crops, pastures, urban. Please advise if this is not correct. Sum of fractional area for psl+crp+pst+urb may not add up to 1 for grid cells with lakes or glaciers. If model does not represent one of the requested tiles, then should be reported as missing value. In cases where more than one land use tile shares information (e.g., if pastureland and cropland share same soil column), then duplicate information should be provided for both tiles. Further details on tile reporting available in the LUMIP GMD paper. Regards, Dave
