AeroCom working group DUST
Participants[edit | edit source]
Ginoux, Balkanski, Mahowald, Schulz, Miller, Tegen, Zender, Winker, Mann, Takemura, (Textor)
- NEXT Telephone conference: probably march 07, organised from NCAR
Goals[edit | edit source]
Investigate the possible climate impact of anthropogenic dust sources
Compare dust simulations to multiple observational datasets
Recommend properties for dust size and refractive index
Short term actions[edit | edit source]
- Provide specifications for a land use related dust source
to be implemented by participating modellers (Mahowald)
- Pull out of dust variables for one AeroCom model (Schulz)
- passed on to R. Miller for initial testing of Cakmur analysis
- establish an observational database beyond Cakmur et al and AeroCom
- revisit HTAP dust experiment design (see MS email to AeroCom in Dec)
- eventually come together at AGU Acapulco conference in May 2007
- suggest input for C. Zender for Perrugia conference
List of Observational data to be included in analysis[edit | edit source]
Al in ocean water
Visibility
IDDI index
Satellite AOD in dust dominated regions (MISR, MODIS, TOMS, DEEPBLUE-MODIS, CALIPSO, Aeronet, Calipso)
Coarse mode satellite derived AOD in dust regions?
Deposition DIRTMAP, Fe, Ca in rain
Surface concentrations Aeroce, Asian network
Refractive index and size in literature
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
