Alaska and the United States are covered by this dataset of weekly, 30-meter resolution Landsat ETM+ mosaics from 2003 to 2012. It provides Top of Atmosphere reflectance, brightness temperature, and NDVI composites designed for regional land surface assessments. The data is part of the NASA Web-Enabled Landsat Data (WELD) project, a collaboration between NASA, USGS EROS, and South Dakota State University.
Dataset WELDAKWK.015 was decommissioned on December 2, 2019. Users are encouraged to use the improved monthly Global Web-Enabled Landsat Data (GWELD) Version 3, 3.1, and 3.2 datasets. Data is distributed in HDF4 format.
