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
Methods: Document model parameterisations Assemble observed vertical profiles to evaluate models PBL vs. Troposphere, look at mesoscale models Exchange modules (use in the same GCM, link to GMI)
Short-term actions/experiments: Compare AeroCom data to observations Redo simulation for 2003 with specific diagnostics Passive tracer experiment (HTAP CO-experiments)
Data to look: vertical distribution ground-based networks: lidar backscatter (corrected), extinction ARM MPLNET EARLINET satellites: GLASS, MISR?, CALIPSO aircraft campaigns
