AeroCom working group DUST


Participants for analysis[edit | edit source]

Ginoux, Balkanski, Mahowald, Schulz, Winker, Mann, Takemura, Miller?, Tegen?, Zender?,

NEXT Telephone conference: 10th of January 17 UTC (= 18 Paris time, 12 ET, 10 Boulder Time?)

Goals[edit | edit source]

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[edit | edit source]

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[edit | edit source]

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[edit | edit source]

The AeroCom database has unanalysed data on dust deposition and wind speed statistics in some models.

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?

Sink repartitioning among AeroCom models
