Composites were created from Level L1T orthorectified scenes using top-of-atmosphere (TOA) reflectance, with the most recent pixel in the 8-day period used as the composite value. The NDWI, derived from Near-IR bands, indicates liquid water content. This collection is complete as of May 1, 2017, and has been superseded by a newer dataset. USGS requests appropriate citation when using the data.\n"]]
