Concert
CONtrail and Cirrus ExpeRimenT
6 Flights
1 Test Flight
5 Scientific Flights
Coordination: Christiane Voigt, AEROTROP Group, DLR/Uni MZ
Scientific Goals
- Detection of microphysical, chemical and radiative
properties of contails and natural cirrus clouds to allow for
a better estimate of their impact on climate.
Main Questions:
- What are microphysical, radiative and chemical
properties of contrail-cirrus?
- How do they evolve with contrail age?
- How do they compare to natural cirrus?
2 Parts:
- CONCERT CHEMISTRY (with AMS)
- CONCERT 2 CONTRAILS (without AMS; with Aerosol Rack of DLR-IPA)
