AeroCom working group DUST
Participants for analysis
Ginoux, Balkanski, Mahowald, Schulz, Winker, Mann, Takemura, Miller?, Tegen?, Zender?,
Goals
Investigate the possible impact of anthropogenic dust sources
Compare dust simulations to multiple observational datasets
Recommend properties for dust size and refractive index
Processes and possible Diagnostics
Dust erosion - wind frequency and speed ; threshold velocities; effective source fluxes; source size distribution
Dust settling - dry removal velocities per size bin;
Wet Dust removal - wet scavenging efficients; vertical distribution; wet deposition of Calcium, dust;
Scattering and absorption - refractive index; AOD; size; absorption
Short-term actions/experiments
Organise regular teleconferences
Prepare a natural and an anthropogenic dust source for a joint
experiment
Follow up on ideas from earlier Mahowald publications.
Assemble observations
(Visibility, IDDI, MISR, MODIS, MODIS Deepblue, Deposition, Aeronet,
Aeroce, Calipso, Asian dust observations, Ca concentrations in rain)
Retrieve from AeroCom database dust variables and wind speed fields
Eventually participate in dust conference in Italy
Data to look at
Aeronet dust dominated sites
Refractive index and size in literature
Dust, Fe and Ca concentrations in air and precipitation
Satellite AOD in dust dominated regions (MISR, MODIS, TOMS, DEEPBLUE-MODIS, CALIPSO)
Fine mode AOD in dust regions?
