Global monitoring of trace gases and aerosols is challenging but essential to understanding atmospheric processes and changes. Mobile commercial platforms offer obvious advantages, and while their use has been limited, an increase in activity is apparent. CARIBIC, CONTRAIL, and MOZAIC conduct regular airborne measurements from onboard commercial aircraft with datasets extending back nearly two decades. These systems regularly probe parts of the atmosphere, especially the tropopause region, that are otherwise studied only episodically by aircraft campaigns, and cannot be studied in great detail by satellite-based remote sensing. Additionally, there are regular measurements from onboard trains (TROICA) and onboard sea-going vessels (PGGM). The data collected within these projects complement data from ground based networks, satellite observations, and measurement campaigns and are extremly valuable for model and satellite validation.

This session focuses on regular atmospheric observations from commercial platforms, in particular aircraft. This includes the analysis of long timeseries, spatial and temporal variations on all scales, vertical profiles, atmospheric transport processes such as stratosphere-troposphere-exchange or long-range transport. Particularly welcome are contributions on modelling on the basis of such data as well as satellite validation studies.
