FLDAS Vegetation Class and Landmask

FLDAS Vegetation Class Illustrations

The land/water mask and the land cover data used in FLDAS Noah and Noah-MP land surface model simulations are based on the IGBP modified Moderate Resolution Imaging Spectroradiometer (MODIS). The University of Maryland land cover data are used in the FLDAS-Forecast Catchment land surface model (CLSM) simulations.

The IGBP modified MODIS land cover classifications are illustrated below and can be downloaded from HERE.

FLDAS Land/Sea Mask

FLDAS adopted the MOD44W MODIS Water Mask as the standard land/sea mask. The mask data [Carroll et al, 2009] is produced at University of Maryland and described here. In order to create the land/sea mask on this page, the percent coverage of 0.01 degree water pixels in each FLDAS grid box was used such that grid boxes made up of more than 50% water were assigned a "water" value of 0 in the FLDAS land/sea mask, while all other grid boxes received a "land" value of 1.
