MODIS Terra Daily NDWI [deprecated]

  • This MODIS Terra Daily NDWI dataset is deprecated and has been replaced by a newer version (MODIS/MOD09GA_006_NDWI).

  • The dataset provides daily global Normalized Difference Water Index (NDWI) values derived from MODIS surface reflectance data.

  • NDWI, ranging from -1.0 to 1.0, indicates changes in liquid water content within vegetation canopies.

  • The dataset covers the period from February 24, 2000, to March 30, 2017, and is freely available for research, education, and non-profit use through Google Earth Engine.

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.
