The Harmonized Landsat and Sentinel-2 (HLS) project is a NASA initiative aiming to produce a seamless surface reflectance record from the Operational Land Imager (OLI) and Multi-Spectral Instrument (MSI) aboard Landsat-8/9 and Sentinel-2A/B remote sensing satellites, respectively. The HLS Version-2.0 data are available now with global coverage (except for Antarctica). With four sensors currently in this virtual constellation, HLS provides observations once every three days at the equator and more frequently with increasing latitude. But getting an observation every three days does not mean getting a clear view of the ground every three days; in most areas of the world clouds frequently obstruct the view. These animations show a year's worth of HLS data near Columbus, Nebraska from 2022. One animation includes the cloudy scenes and the other has cloud-free or mostly cloud-free scenes.
