Summary

The 22th AeroCom / 11th AeroSAT meeting will be hosted by PNNL (Pacific Northwest National Laboratory)

The major objectives of recent AeroCom/AeroSAT meetings are:

- update the outcome of the Phase III AeroCom model experiments
- discuss challenges for aerosol modeling raised through CMIP6 and related activities
- formulate new AeroCom and AeroSAT activities of modeling and analysis
- discuss near term goals and direction
- discuss evolving strengths and limitations of satellite retrievals

AeroCom is an open international initiative of scientists interested in the advancement of the understanding of global aerosol properties and aerosol impacts on climate, weather, and air quality. A central goal is to more strongly tie and constrain modeling efforts to observational data from satellite, ground-based, and aircraft observations. A major element for exchanges between data and modeling groups are annual meetings of AeroCom together with the satellite data oriented initiative AeroSAT. In addition to the comparisons among models and between models and data, AeroCom initiates and coordinates model experiments to target particular research topics, leading to joint research papers of synthesizing character. A common database is maintained at the Norwegian Meteorological Institute to facilitate joint scientific exploration. AeroCom encourages submissions covering (1) ongoing and planned activities that use AeroCom data, (2) comparisons of model simulations to observations and (3) novel ideas including the representating aerosol cloud interactions.  
 

AeroSAT is an international consortium of experts on aerosol remote sensing from ground, aircraft and space. This initiative was established in 2013: (1) to accelerate the exchange of ideas and concepts both within the aerosol remote-sensing community, and in conjunction with the aerosol modeling (e.g., AeroCom), and in situ aerosol-measuring efforts, and (2) to advance and coordinate the capabilities of satellite sensor aerosol retrieval products, which are needed to constrain aerosol processing and assist in evaluating global modeling. One major aspect of AeroSAT is the interaction with the aerosol modeling community as every year, AeroSAT meets in conjunction with AeroCom, and cross-pollination of ideas will be the focus of an overlap half-day joint session with AeroCom. The main goal of the AeroSAT meeting overall is to share and encourage new developments and ideas in several major areas, including aerosol-type retrievals, characterizing aerosol amount and type product uncertainties, creating long-term data records, and improving aerosol measurement-model interactions. On each of these AeroSAT topics, working groups have ongoing, dedicated efforts, and will report briefly on their activities, followed by extensive open discussion. Each session will be introduced by one or two invited seed presentations to stimulate discussion. As appropriate, posters are accommodated based on submitted abstracts, and in some cases, one or two abstracts are selected for very brief oral presentations on new approaches, also as part of the introduction to discussion.
