AI-generated Key Takeaways
-
This dataset, providing the Normalized Difference Water Index (NDWI), is now superseded by MODIS/MOD09GA_006_NDWI.
-
The NDWI is derived from Near-IR and another IR band and is sensitive to changes in the liquid water content of vegetation canopies.
-
The dataset is available daily, globally, covers the period from 2000 to 2017, and is provided by Google Earth Engine.
-
MODIS data has no restrictions on subsequent use, sale, or redistribution.
-
Earth Engine is free to use for research, education, and nonprofit purposes, requiring registration for access.

Description
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.
