The Operational Land Imager (OLI) is housed aboard the joint NASA/USGS Landsat 8 and Landsat 9 satellites, while the Multi-Spectral Instrument (MSI) is mounted aboard Europe's Copernicus Sentinel-2A and Sentinel-2B satellites. The combined measurement enables global observations of the land every 2 to 3 days at 30m 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. The HLS project distributes data as two separate products: HLSL30 (Landsat 8/9) and HLSS30 (Sentinel-2 A/B). They both provide 30m Nadir Bidirectional Reflectance Distribution Function (BRDF), Adjusted Reflectance (NBAR).
