MCD19A2.006: Terra & Aqua MAIAC Land Aerosol Optical Depth Daily 1km [deprecated]

  • This dataset, MCD19A2 V6, has been superseded by a newer version (MODIS/061/MCD19A2_GRANULES) and is considered deprecated.

  • It provides daily, 1 km resolution data on land aerosol optical depth (AOD) derived from MODIS Terra and Aqua satellites using the MAIAC algorithm.

  • The dataset covers the period from February 26, 2000, to February 17, 2023, and includes bands for AOD at different wavelengths, uncertainty, and atmospheric properties.

  • Users can access the data through the Earth Engine platform with the provided snippet ee.ImageCollection("MODIS/006/MCD19A2_GRANULES").

  • There are no restrictions on the use, sale, or redistribution of this data.
