How does WRF calculate albedo?

Post by kwerner » Wed Aug 29, 2018 11:30 pm

If you map data to the 24-category USGS data, then albedo will be given at the model start time, based on the LANDUSE.TBL. Since the initial value is dependent on the landuse type, however, the Noah LSM does not use the albedo (or any other land properties) from the LANDUSE.TBL. It uses values from the VEGPARM.TBL, and albedo is computed based on vegetation fraction, and bounded by the max and min values given in the VEGPARM.TBL.
