Abstract
Tropospheric aerosols have a significant influence on climate and have been recognised by the Intergovernmental Panel on Climate Change as the biggest source of uncertainty in understanding future climate, yet the factors controlling their spatial distribution remain unclear. Despite new observations from the UK ATSR instruments and the MODIS and MISR instruments (on NASA's Terra satellite) there are still open questions about aerosol sources, sinks, microphysical properties and the aerosol vertical distribution.
A three-dimensional dust lifting and transport model, using meteorological fields from ECMWF analyses, is used to compare predicted mineral dust loading over the Sahara with observations of optical depth from AERONET, SEVIRI, AATSR, and MISR. The model is used to investigate the sensitivity of the predicted aerosol profiles to variations in model parameters, including desert dust emission. Estimates of yearly emissions, depositions, and mass fluxes into the Atlantic are presented.
