 ### About HLS
 The Harmonized Landsat and Sentinel-2 (HLS) project provides consistent surface reflectance data from the Operational Land Imager (OLI) aboard the joint NASA/USGS Landsat 8 and 9 satellites and the Multi-Spectral Instrument (MSI) aboard the European Union’s Copernicus Sentinel-2A and Sentinel-2B satellites. The combined measurements between Landsat 8, Landsat 9, Sentinel-2A, and Sentinel-2B enable global observations of the land every 2-3 days at 30 meter (m) spatial resolution. The HLS project uses a set of algorithms to obtain seamless products from OLI and MSI that include atmospheric correction, cloud and cloud-shadow masking, spatial co-registration and common gridding, illumination and view angle normalization, and spectral bandpass adjustment.
 
+NOTE: Stray swaths of incorrectly dated imagery may appear near the dateline by eastern Australia/New Zealand due to an artifact caused by USGS and ESA using UTC time to name the Landsat and Sentinel-2 Level 1 products. The observations are labeled one day early with respect to the local time.
