Aircraft operating at cruise altitudes are the only direct anthropogenic emission sources in the tropopause region at altitudes of 8 to 12 km. Aviation contributes significanly to global warming through emissions of carbon dioxide, nitrogen oxides, aerosol and specifically through aircraft induced cloud modifications. At present, large uncertainties hinder the targetted reduction of individual climate effects from aviation.
Clouds have a multifold impact on the atmosphere. They change the radiation budget, modify the hodrological cycle, offer sites for heterogeneous reactions and transport trace gases to different regions. Particularly the trace gas uptake in ice clouds is not understood in detail.
The aim of the Junior Research Group AEROTROP is to study heterogeneous chemistry on atmospheric particles with a specific focus on aircraft emissions in a wholistic approach combining aircraft measurements, satellite observations, process studies and global modeling.
The Junior Research Group is a 6 years project funded by the Helmholtz association (HGF), the German Aerospace Center (DLR), the university of Mainz, and the Max-Planck-Society (MPG). The team consists of 8 members working at DLR, MPI-C and University of Mainz.
The AEROTROP team has organized the aircraft campaign CONCERT - CONtrail and Cirrus ExpeRiment
