OMI-MODIS aerosol direct radiative effect over clouds, version 1.0

The OMI-MODIS above-cloud aerosol Direct Radiative Effect (DRE) database is available for all cloud scenes in an area over the south-east Atlantic (20W - 10E, 20S - 10N) from 2002 to present during the months June - October. This is a period of massive vegetation burning in southern Africa during the dry season and often smoke plumes can be observed drifting over the Atlantic ocean. The aerosol DRE from OMI-MODIS indicates the warming effect of the smoke when it overlies clouds due to absorption of sunlight. This is measured in Watts per square meter (W/m2). <br> The data are accompanied by images that show an overview of the warming effect on a particular day. The OMI-MODIS aerosol DRE is overplotted over MODIS RGB showing clouds. <br> The database is described in the following paper: <br> M. de Graaf, L.G. Tilstra, and P. Stammes, Aerosol direct radiative effect over clouds from a synergy of OMI and MODIS reflectances, Atmos. Meas.
