Facility for Airborne Atmospheric Measurements (FAAM) Aircraft Data for the Dust and Biomass EXperiment (DABEX)
The Dust And Biomass EXperiment, (DABEX), based in Niamey, Niger in early 2006, investigates the radiative effect of dust and biomass aerosols emitted from the Sahara/Sahelian regions. The interaction of dust and biomass over this region has not previously been well-established. The new GERB and SEVERI instruments onboard the geostationary MSG satellite platform provide ideal tools for monitoring the evolution of the dust and biomass plumes. Radiometers onboard the FAAM BAE-146 aircraft in conjunction with surface based sun-photometers will determine the accuracy of the retrieval algorithms in terms of the aerosol optical depth, size distribution, and refractive indices.
The main objectives of DABEX are:
-to perform high quality in-situ and remote sensing measurements of the optical and physical properties of anthropogenic biomass burning aerosols from sub-Sahelian west Africa;
-to perform high quality in-situ and remote sensing measurements of the optical and physical properties of natural mineral dust aerosols from over sub-Sahelian west Africa;
-to determine the interaction between the anthropogenic biomass burning aerosols and natural mineral dust aerosols using a combination of chemical, physical and optical measurements;
-to provide high quality spectral measurements of the solar and terrestrial radiative effects of both biomass burning aerosol and mineral dust aerosol;
-to determine the consistency between in-situ measurements/ satellite and surface-based remote-sensing methods of the effects on the radiation budget of the Earth of the composite biomass and mineral dust aerosols;
-to model the effect of the biomass and mineral dust aerosols on a regional and global scale and estimate the impact on the global radiation balance of the Earth/Atmosphere system.
