Does Landsat Level-1 data processing include atmospheric correction?


While Landsat Level-1 data are not corrected for atmospheric conditions, the USGS now offers higher-level science data (also known as Level-2 or Surface Reflectance), that have atmospheric corrections applied. Surface Reflectance data and derived Spectral Indices are available to all users.


Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
