This dataset collection contains Global Aerosol Optical Depth data produced within the Earth Observation Climate Information Service (EOCIS) project by Swansea University.

The data have been derived by applying the Swansea University algorithm to the Along-Track Scanning Radiometer-2 (ATSR-2), Advanced Along-Track Scanning Radiometer (AATSR) and Sea and Land Surface Temperature Radiometers (SLSTR-A and SLSTR-B).

The data are grouped into two instrument families each with an associate daily and monthly product. The ATSR-2 and AATSR instruments have been grouped as (A)ATSR L3C v4.35.1 products. SLSTR-A and SLSTR-B are grouped as SLSTR L3C v1.14.1 products.

The combined data collection covers the periods 1995-2012 and 2016 to present.
