Doppler wind lidar for in-flight turbulence mitigation
Turbulence, gusts and wake vortices pose a significant risk to today’s and future civil airliners representing the second major cause for enroute accidents in civil aeronautics, with increasing trend. Hence, the Lidar department at IPA develops a novel lidar sensor for the purpose of close-range turbulence detection and immediate flight control reaction.

In-situ instrumentation: Trace species
The Institute of Atmospheric Physics develops, modifies and optimizes in-situ instrumentation for the airborne measurements of a series of trace gases. The instruments are deployed on different aircraft (HALO, DLR Falcon, Geophysica-M55, Lufthansa A340-600).

In-situ instrumentation: Clouds
The Institute for Atmospheric Physics operates a variety of different sensors for the detection and characterization of cloud particles on the research aircraft HALO and Falcon. The size range of the measured particles expands from sub-micrometers to several millimeters and thus covers all types of clouds and their growth phases.

Passive remote sensing
Satellite or ground based passive remote sensing from satellite utilize either solar radiation reflected at the Earth's surface or scattered in the atmosphere, or thermal radiation emitted by the surface-atmosphere system. At the Institute of Atmospheric Physics our remote sensing activities especially focus on water and ice clouds as well as on contrails and aerosols (also volcanic ash).

Polarimetric Doppler radar (POLDIRAD)
On the roof of the institute the polarimetric Doppler radar POLDIRAD has been operated since 1986. Measurements of the Doppler velocity are meanwhile standard for operational radars, but in Europe only POLDIRAD is able to transmit and receive with any possible polarisation. Together with the bistatic receivers it is now possible to estimate the full 3D wind field within a precipitation field, e.g. a thunderstorm.
