| − | ===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

| − | The first months of Calipso data should be a primary goal for
| |
| − | a joint experiment. July-August 2006. Emissions from biomass burning
| |
