AeroCom

The primary objective of AeroCom meetings is to share and participate in efforts
to untangle the complexity in bottom-up aerosol component modules
in global modeling. Better process understanding is addressed through either
common experiments with harmonized input, assumptions and parameterizations
or data constraints from observations. The data aspect is also the major reason
to co-locate AeroCom and AeroSAT for exchange on data potential and data needs.

 

key AeroCom topics

- history of Aerosol Forcing 2014-1850  (what is anthropognic? what in natural?) in AeroCom/AerChemMIP
- how do models simulate natural aerosol (dust and seasalt components have large diversities!)
- indirect forcing and observational constraints (e.g. what we learn from volcanic cases or satellite statistics)
- evaluations to observations (satellite data / ground / planes)  ?    (consistency in anomalies/trends ?)
- unresolved issues (for phase IV?) : water uptake / size / natural aerosol / transport via tracers?
- discuss strategies to improve global aerosol models
- understand aerosol impact on climate evolution


AeroSAT

The primary purpose of the AeroSAT meeting is to assess the state-of-the-art
of satellite aerosol retrievals and products, brainstorm ideas, and develop
consensus as much as possible. AeroSAT is designed as a meeting of experts.
So, as is our practice, the meeting format will feature brief overview talks on key issues, occasional updates on specific new developments, chairperson-presented
discussion points, and ample time for discussion, Thus,
presentations on
individual scientific work are deferred to poster-presentations.
Oral seed presentations at the start of each session are by invitation
- to provide a broader overview
- to introduce new approaches and
- to stimulate subsequent discussions on related issues and challenges

 

key AeroSat topics

- new elements/opportunities in/from remote sensing
- climate data records (are they useful/accurate enough? for AeroCom? how can they be improved?)
- pixel uncertainty (have they helped in data assimilations?)
- aerosol typing (can we agree on definitions? on quantitative (optics?) measures? interpretive enough for forward and inverse modeling?)
- aerosol indirect effects (how best to use satellite data relationships to constrain aerosol-cloud interaction processes and modeling?)
- AeroSAT experiments
- best practices for gridded level 3 data
