Detailed Description

Harmonized Landsat and Sentinel-2 (HLS) data are here!

The LP DAAC and the HLS Science Team are pleased to announce the release of Harmonized Landsat and Sentinel-2 (HLS) version 2.0 surface reflectance products. HLS data are composed of observations from Landsat 8 and Sentinel-2 and provide a set of seamless data products that can be utilized as if all observations were obtained from a single sensor, providing a global observation of the land every 2-3 days at 30-meter spatial resolution. This is beneficial for observing volcanoes around the world. This video shows eruption activity, and vegetation loss due to eruption activity, over Mount Stromboli stratovolcano in Italy from July 2 to August 8, 2019.

Data are now available for this past month with historical and forward processing on-going. Once the historical processing has been completed the L30 data will be available from May 2013 to present and the S30 data will be available from December 2015 to present.
