We estimate the surface area (SA) of ground-level particulate matter by combining Aerosol Optical Depth (AOD) retrievals from the NASA MODIS and MISR instruments with aerosol vertical profile and scattering properties simulated by the GEOS-Chem chemical transport model.

Google Earth Datasets:
A small selection of regional Mean Satellite-Derived Surface Area estimates have been cut for import into Google Earth, available [here]. These correspond to 2001-2010 surface area. Click on placemarks labelled ‘Surface Area’ for the legend. For additional regions, please contact Aaron van Donkelaar (aaron.vandonkelaar@wustl.edu).

Scientific Datasets:
Global resolved datasets are provided in an ArcGIS-compatible ASCII file. Country means are provided in a comma separated ascii (.csv) format. Other extractions can often be produced upon request. Please contact Aaron van Donkelaar (Aaron.van.Donkelaar@dal.ca) for further information.
