MCD19A2 - MODIS/Terra+Aqua Land Aerosol Optical Depth Daily L2G Global 1km SIN Grid
MCD19A2 is the shortname for the Multi-Angle Implementation of Atmospheric Correction (MAIAC) algorithm-based Level-2 gridded (L2G) aerosol optical thickness over land surfaces product. Derived using both Terra and Aqua MODIS inputs, this L2 product is produced daily at 1 km pixel resolution. This product helps generate a number of atmospheric and geometric properties/parameters that are used to produce another facet of the MAIAC algorithm: the land surface Bidirectional Reflectance Factor.
The MCD19A2 product contains two data groups with the following Science Data Set parameters:
- Grid500m group
- Aerosol Optical Depth at 047 micron
- Aerosol Optical Depth at 055 micron
- AOD Uncertainty at 047 micron
- Fine-Mode Fraction for Ocean
- Column Water Vapor in cm liquid water
- AOD QA
- AOD Model (Regional background model used)
- Injection Height (Smoke injection height over local surface height)
- Grid5km group
- Cosine of Solar Zenith Angle
- Cosine of View Zenith Angle
- Relative Azimuth Angle
- Scattering Angle
- Glint Angle
The MCD19A2 product has achieved Stage-3 validation.
