The USGS has developed research-quality, applications-ready, Landsat Level-3 Science Products that are now available for download from EarthExplorer. These products will reduce the amount of time users spend on data processing and provide research-quality, applications-ready information on burned areas, surface water extent and snow cover.
The Landsat Burned Area algorithm is designed to identify burned areas in all ecosystems (e.g. forest, shrubland, and grassland), the Dynamic Surface Water Extent algorithm produces images that represent surface water inundation for each pixel, and the Landsat Fractional Snow Covered Area algorithm produces per-pixel snow cover fraction maps.
All three products are generated from U.S. Landsat 4-8 Analysis Ready Data surface reflectance data collected from the Landsat Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM+), and Operational Land Imager (OLI)/Thermal Infrared Sensor (TIRS) instruments from 1982 to 2017 (Dynamic Surface Water Extent is available 1982 to present). This 36+ year record at 30-meter spatial resolution allows for the discrimination and study of natural and human-induced changes to the Earth’s land surface.

Webinar Recording Available: Advancing Science Capabilities with Data Harmonization & NASA’s Harmonized Landsat Sentinel-2 (HLS) Products
This webinar provides an introduction to HLS data, services, and tools and shows you how to find resources to work with the data; visualize, search for, and access the data through NASA Worldview and Earthdata Search; it also demonstrates how to use the Fire Information for Resource Management System (FIRMS) tool to visualize HLS data to monitor fires and floods.
