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/MYD09GA surface reflectance composites.

The NDWI, with a pixel size of 463.313 meters and a daily cadence, ranges from -1.0 to 1.0, indicating liquid water content in vegetation canopies. The dataset, now superseded, was offered via Google Earth Engine and is free for research, education, and nonprofit purposes. The data has no restrictions on use.\n"]]
