AeroCom wiki discussion entry

Go back to AeroCom/Working group structure

See also summary of AeroCom/Recommendations

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?
