Abstract

This dataset provides global Aerosol Optical Depth (AOD) from the Sea and Land Surface Temperature Radiometers (SLSTR), presented on a 1° latitude-longitude grid, starting in 2016.

The product contains the daily mean and standard deviation of the total AOD and fine-mode AOD at 550nm retrieved within each grid cell. An uncertainty estimate is provided for the total AOD. It also includes a number of associated quantities determined consistently with the retrieval: AOD at 670nm, 870nm and 1600nm and Angstrom exponent, non-spherical dust AOD, absorbing AOD and single scattering albedos all at 550nm.

The data here are part of a set of data that have been produced by Swansea University as part of the Earth Observation Climate Information Service (EOCIS) project, using algorithms developed under the European Space Agency’s (ESA) Climate Change Initiative for Aerosol project. The combined data collection covers the periods 1995-2012 and 2016 to present.
