NLDAS Vegetation Greenness Fraction

This page contains monthly vegetation greenness fraction data files for the NLDAS domain. The data has been re-gridded from NESDIS/NOAA 0.144-degree monthly climatology values from NCEP. The data is a composite of a 5-year (1985-1989) dataset using the AVHRR satellite. Details of the original dataset can be found in Gutman and Ignatov (1997). The twelve monthly greenness fraction fields are assumed to be valid at the 15th of each month. The values are in fractions (although currently illustrated as percentages below).
