The images feature the Normalized Difference Water Index (NDWI), derived from near-infrared bands, indicating liquid water content changes. Composites are created from all scenes within each 32-day period, with the most recent pixel as the composite value. This data is public domain and provided by USGS. The dataset has been replaced by a new one, available at LANDSAT/COMPOSITES/C02/T1_L2_32DAY_NDWI.\n"]]
