Multi-Angle Implementation of Atmospheric Correction (MAIAC)

Overview

Multi-Angle Implementation of Atmospheric Correction (MAIAC), as the name suggests, accomplishes atmospheric correction via a new method that is encoded in a generic algorithm designed to work with Moderate Resolution Imaging Spectroradiometer (MODIS) data to facilitate deriving both aerosol and land surface reflectance products. Based on a time-series of MODIS measurements and spatial analysis, this algorithm simultaneously retrieves atmospheric aerosols and bidirectional reflectance from MODIS data. It further detects clouds and corrects atmospheric effects over both dark vegetated surfaces and bright desert targets.

Collection-6 MAIAC products are in Stage-1 validation. This entails that their product accuracy has been estimated using a small number of independent measurements derived using data from selected locations, time-periods, and ground-truth/field programs.
