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.
Processes and possible Diagnostics
Short-term actions/experiments
Data to look at
Objective: 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
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
horizontal distribution station data (surf conc) networks satellite data (e.g. on dust episodes to pin down horizontal transport)
processes wet deposition of SO4? ??
