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
