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 monthly products from GOMOS, using the AERGOM algorithm, version 2.1 and was produced by BIRA (Belgian Institute for Space Aeronomy).

The data are stored as monthly averages and standard deviations of a range of aerosol variables, on global 2.5 degree x 10 degree latitutude/longitude grids, and in NetCDF format. The horizontal resolution is 0.5km.

The variables included are: Stratospheric Aerosol Optical Depth (AOD), Angstrom coefficient, extinction profile.

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