1 km MODIS-based Maximum Green Vegetation Fraction

Maximum Green Vegetation FractionDescription: These data describe annual maximum green vegetation fraction (MGVF), and are based on 12 years (2001-2012) of Collection 5 MOD13A2 normalized difference vegetation index (NDVI) data. Each map shows MGVF for one year (as well as the average, for all years from 2001-2012), based on the annual maximum NDVI and linear mixing models that describe green vegetation fraction (vs. non vegetated area) for each land cover class for each year. Generation of these data is described in Broxton et al., 2014b. The data has been re-gridded from the MODIS sinusoidal grid to a regular latitude-longitude grid, and the map has 21600x43200 pixels (corresponding to a resolution of 30 arc seconds).

Values range from 0 (corresponding to 0% vegetation cover) to 100 (corresponding to 100% vegetation cover).

Format: The data are provided in GeoTIFF format (as 8-bit unsigned integers), and compressed (which reduces the file size from 890 mb to about 100 mb per map).
