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 2 aerosol products from AATSR, using the ORAC algorithm, version 3.02.

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