Abstract

The ESA Climate Change Initiative Aerosol project has produced a number of global aerosol Essential Climate Variable (ECV) products from a set of European satellite instruments with different characteristics.

This dataset comprises the Level 3 aerosol daily products from AATSR, using the Swansea University (SU) algorithm, version 4.2.

For further details about these data products please see the documentation.
