The LP DAAC is pleased to announce the availability of the Observational Products for End-Users from Remote Sensing Analysis (OPERA) Land Surface Disturbance Alert from Harmonized Landsat Sentinel-2 (HLS) Version 1 data product. This product maps vegetation disturbance using inputs from the Operational Land Imager (OLI) aboard the Landsat 8 and Landsat 9 satellites and the Multi-Spectral Instrument (MSI) onboard the Sentinel-2A/B satellites. Vegetation disturbance is detected when there is an indicated decrease in vegetation cover within an HLS pixel. The OPERA Land Surface Disturbance Alert data product maps land disturbance every 2-4 days at 30 meter (m) spatial resolution.
Users of the broader science and applications community are encouraged to check out OPERA’s Stakeholder Engagement Program (SEP) where they can learn more about OPERA data and provide feedback.
