It is deprecated and superseded by a newer dataset. The data, from the USGS, is presented as 32-day composites using the Normalized Difference Water Index (NDWI), which is useful for observing vegetation liquid water content. This collection is complete, as the USGS stopped producing pre-collection Landsat.\n"]]
