Landsat Surface Reflectance Quality Assessment

By Landsat Missions

Landsat Surface Reflectance products include Quality Assessment (QA) bands to identify the pixels that exhibit adverse instrument, atmospheric, or surficial conditions. Used effectively, QA information improves the integrity of science investigations by indicating which pixels might be affected by instrument artifacts or subject to cloud contamination.
