True surface color, harmonized daily (Landsat, 30 m)

HLS Landsat Operational Land Imager Surface Reflectance and TOA Brightness Daily Global 30m v2.0
land NASA LPCLOUD Level 3 active COG
In plain English

What it measures. This gives the true reflected color of the land surface at 30-meter detail, cleaned of the atmosphere's effects so the same ground looks consistent over time. It pairs with the matching Sentinel-2 product so the two can be stacked together.

How it's made. Derived from the Landsat 8 and 9 satellites' Operational Land Imager, then atmospherically corrected, cloud-masked and aligned to a common grid so it blends seamlessly with Sentinel-2 imagery.

How & where you'd use it. Good for tracking crops, forests, water and land-cover change frequently and at fine detail, since combining Landsat and Sentinel-2 gives a clear view of the land every day or two.

Official description

The Harmonized Landsat Sentinel-2 (HLS) project provides consistent surface reflectance (SR) and top of atmosphere (TOA) brightness data from a virtual constellation of satellite sensors. 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, 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 HLSL30 product provides 30-m Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Reflectance (NBAR) and is derived from Landsat 8/9 OLI data products. The [HLSS30](https://doi.org/10.5067/HLS/HLSS30.002) and HLSL30 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 HLSL30 product is provided in Cloud Optimized GeoTIFF (COG) format, and each band is distributed as a separate file. There are 11 bands included in the HLSL30 product along with one quality assessment (QA) band and four angle bands. See the User Guide for a more detailed description of the individual bands provided in the HLSL30 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.
