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
Follow up on ideas from earlier Mahowald publications.
(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?
