The Belgian Institute for Space Aeronomy (BIRA-IASB), Brussels, Belgium, and the Max-Planck-Institute for Chemistry (MPI-C), Mainz, Germany, jointly host a virtual
International Workshop on MAX-DOAS and other scattered light DOAS systems: instruments, techniques and applications
Over the last years, a growing number of Multi-AXis (MAX) and other scattered light DOAS instruments is operated world wide. By probing the troposphere in different viewing angles and from different platforms, vertical profile information on aerosols and tropospheric trace gases, in particular NO2, can be derived.

Thereby, scattered light DOAS instruments provide an essential link between in-situ measurements of trace gas concentrations and column-integrated measurements from satellite, and thus play a key role in satellite validation. This workshop is open for contributions about

- MAX-DOAS and other scattered light DOAS instrumentation and operation on various platforms (ground-based, mobile, aircraft)
- trace gas retrievals
- inversion algorithms
- identification and treatment of clouds
- comparisons to in-situ or satellite measurements and models
- new developments - scientific results.>

The workshop will take place on 11-12 May 2021 in one or two webex sessions during afternoon (European time) to allow attendance from different parts of the world.

Please submit your short abstract (max. 200 words) until 28 February 2021

or announce your participation without abstract until 30 April 2021

via email to: steffen.beirle@mpic.de with subject [MAXDOAS-WS].

The schedule will be finalized by end of March 2021.
