Beschreibung: Trace gases are emitted to the atmosphere from ground sources. Within the atmosphere these trace gases undergo chemical and physical processes which can result in the production of atmospheric pollutants like ozone and secondary organic aerosols. Dependent on the time scale of these processes and the diurnal evolution of the planetary boundary layer the vertical distribution of the trace gases and aerosols can vary significantly with height and time of the day. Established observation networks for the atmospheric chemical composition predominately use ground measurement stations and are spatially limited. Recent developments of serial drones provide the feasibility for a mobile exploration of the vertical trace gas distribution within the atmosphere. However, the application of serial drones requires the development and use of miniaturised sensors.
This project comprises the specification and application of miniaturised sensors for the vertical profile dependent measurement of trace gases and meteorological parameters on-board of an ultra-lightweight serial drone.

The goals are:

• adapt newly developed sensors with respect to weight, time resolution, selectivity, sensitivity and power consumption to the requirements of a serial drone and atmospheric conditions.
• optimize the electronic accessories and the data acquisition
• test and characterize the miniaturised sensors in the lab
• apply the sensors on-board of a drone for atmospheric measurements of trace gases and aerosols
• compare vertical profiles measured to those of the meteorological tower of the research centre Jülich
