The Normalized Difference Water Index (NDWI) is sensitive
to changes in liquid water content of vegetation canopies. It is
derived from the Near-IR band and a second IR band, ≈1.24μm when
available and the nearest available IR band otherwise. It ranges in
value from -1.0 to 1.0. See
Gao (1996)
for details. This product is generated from the MODIS/MOD09GA surface reflectance composites.
