The 19th AeroCom / 8th AeroSAT workshops 2020

will be held as virtual ZOOM meeting (due to COVID-19)
hosted by K.Tsigaridis

Oct 12-16, 2020

registration is open (now until August 21)

register and abstract submission via this website under
"AeroCom and AeroSAT Workshop Registration"

the program will be announced at the end of August

we encourage submissions of abstracts covering any ongoing or planned activity that uses AeroCom data. Analyses that use Phase III data will be prioritized for oral slots. Talks on aerosol modelling improvements or comparisons against observations, aerosol-climate interactions and novel research ideas are also encouraged

A 'focused' poster presentations format
of your research is encouraged due to
- the reduced workshop time
- the uncommon workshop format

Even if you are given (eventually) an oral pesentation
please also consider to submit a poster with major
research results ... already well before the workshop
(in order to share content and help focus discussions)
 
- posters (pdf or ppt) are requested to be sent
by September 27 to stefan.kinne@mpimet.mpg.de
(for viewing and sharing well before the ZOOM meeting)

- poster slides (wide ppt format) for oral introductions
of posters should be sent
by October 4 to stefan.kinne@mpimet.mpg.de

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
