True surface color, harmonized daily (Sentinel-2, 30 m)

HLS Sentinel-2 Multi-spectral Instrument Surface Reflectance Daily Global 30m v2.0
land NASA LPCLOUD Level 3 active COG
In plain English

What it measures. This provides the true reflected color of the land at 30-meter detail, corrected for the atmosphere so the surface looks consistent from one date to the next. It is designed to stack directly with the matching Landsat product.

How it's made. Derived from the Multi-Spectral Instrument on Europe's Sentinel-2A, 2B and 2C satellites, then atmospherically corrected, cloud-masked and aligned to a shared grid with Landsat imagery.

How & where you'd use it. Used to monitor agriculture, forests, water and land change frequently and in fine detail, with Sentinel-2 and Landsat together giving a fresh look at the land every day or two.

Official description

The Harmonized Landsat Sentinel-2 (HLS) project provides consistent surface reflectance data from the Operational Land Imager (OLI) aboard the joint NASA/USGS Landsat 8 satellite and the Multi-Spectral Instrument (MSI) aboard Europe’s Copernicus Sentinel-2A, Sentinel-2B, and Sentinel-2C satellites. The combined measurement enables global observations of the land every 1.6 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. The HLSS30 product provides 30-m Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Reflectance (NBAR) and is derived from Sentinel-2A, Sentinel-2B, and Sentinel-2C MSI data products. The HLSS30 and [HLSL30](https://doi.org/10.5067/HLS/HLSL30.002) products are gridded to the same resolution and Military Grid Reference System ([MGRS](https://hls.gsfc.nasa.gov/products-description/tiling-system/)) tiling system and thus are “stackable” for time series analysis. The HLSS30 product is provided in Cloud Optimized GeoTIFF (COG) format, and each band is distributed as a separate COG. There are 13 bands included in the HLSS30 product along with four angle bands and a quality assessment (QA) band. See the User Guide for a more detailed description of the individual bands provided in the HLSS30 product. The HLS project is funded by NASA’s Satellite Needs Working Group (SNWG) which provides data products developed to meet the needs of stakeholders from US government agencies.
