USGS Landsat Analysis Ready Data (ARD) for the conterminous United States are now available for download from EarthExplorer (see screenshot below).
Landsat ARD is a revolutionary new product that will make the Landsat archive more accessible, easier to analyze, and reduce the amount of time users spend on data processing for time-series analysis. Landsat ARD are derived from Landsat Collections Level-1 precision and terrain-corrected scenes which are then processed and arranged in geospatially calibrated tiles and dense temporal stacks for immediate use in monitoring and assessing landscape change.
Each Landsat ARD tile consists of the following four data layers:
- Top of atmosphere (TA) reflectance
- Brightness temperature (BT)
- Surface reflectance (SR)
Pixel quality assessment (QA)
Landsat ARD documentation and other useful resources are located on the Landsat ARD webpage.
