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 session 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
- scientific results.
Results from intercomparison campaigns like CINDI-2 (2016 in Cabauw) are particularly welcome.
