NLDAS-E Vegetation Greenness Fraction Information

This page contains monthly vegetation greenness fraction data files covering the NLDAS-E domain, and is identical to that used by NCEP's operational Eta model. The data has been re-gridded from the 0.144 degree resolution NCEP global data sets to the NLDAS-E domain. The twelve monthly greenness fraction fields are valid on the 15th of each month. Temporal interpolation is necessary within the ETA/LDAS model to get greenness fraction data for a specific date. The values in the data sets given below are in fractions, ranging from 0.01 to 0.99 over land, and the values are 0.00 over water.
