===Goals===
 
* Understanding of model diversity in spatial distribution and in removal processes
 
* Evaluate simulated spatial distribution and processes with observations
 
* Establish/quantify an acceptable diversity in global aerosol simulations
 
* Find methods to evaluate process parameterisations
 
* Define dedicated diagnostics of model results
 
* Elaborate recommendations
 
* Collect data for model evaluation (vertical profiles&processes) including uncertainty
 
 
 
* This working group has a special focus on dust.
 
 
 
 
 
===Specific scientific questions===
 
* How realistic are the simulated (vertical and horizontal) spatial aerosol distributions?
 
* How to validate aerosol processes?
 
* Is the diversity of simulated vertical dispersal caused by differences in transport or by removal processes?
 
* How much complexity of aerosol models is necessary?
 
* more
 
 
 
 
 
===Processes and possible Diagnostics===
 
Document model parameterisations <br>
 
Assemble observed vertical profiles to evaluate models<br>
 
PBL vs. Troposphere, look at mesoscale models<br>
 
Exchange modules (use in the same GCM, link to GMI)<br>
 
 
 
 
 
===Short-term actions/experiments===
 
Compare AeroCom data to observations<br>
 
Redo simulation for 2003 with specific diagnostics<br>
 
Passive tracer experiment (HTAP CO-experiments)<br>
 
Validate model results with observed vertical LIDAR profiles: Rich and Christiane<br>
 
Ensure a link to the scavenging workshop planned by NCAR and NASA (P. Rash and J. Rodriguez).
 
 
 
The first months of Calipso data should be a primary goal for
 
a joint experiment. July-August 2006. Emissions from biomass burning
 
should be up to date. Charles Ichoku proposed to prepare an
 
emission dataset based on radiative power energy and MODIS fire spots.
 
Guido van der Werf is investigating the burnt area product readiness.
 
 
 
===Data to look at===
 
* vertical distribution
 
ground-based networks: lidar backscatter (corrected), extinction ARM MPLNET EARLINET<br>
 
satellites: GLASS, MISR?, CALIPSO
 
aircraft campaigns
 
 
 
* horizontal distribution
 
station data (surf conc) networks<br>
 
satellite data (e.g. on dust episodes to pin down horizontal transport)<br>
 
 
 
* processes
 
wet deposition of SO4?<br>
 
??
 
 
 
 
 
===Contact persons/experts===
 
provide vertical profile LIDAR data: Rich Ferrare<br>
 
CALIPSO: Dave Winker<br>
 
MISR: Ralph Kahn <br>
 
Access to AeroCom data base: Christiane Textor<br>
 
Dust questions: Paul Ginoux<br>
