US National Aeronautics and Space Administration (NASA) Terra/Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) Level 2 Land Aerosol Optical Depth Product (MCD19A2), Version 6.1

The MCD19A2 is part of the Moderate Resolution Imaging Spectroradiometer (MODIS) suite of data products. It is specifically designed to provide aerosol optical depth (AOD) measurements over land. It uses the Multi-Angle Implementation of Atmospheric Correction algorithm to retrieve AOD data, which is crucial for understanding air quality, environmental changes, and atmospheric processes.
