HALO-ML-Cirrus Mission Status

Investigate the climate impact from cirrus and contrail cirrus

Natural cirrusMeasure microphysical, optical and radiative properties of cirrus clouds with improved „state-of-the-art“ instrumentationInvestigate the development of macroscopic, microphysical, and radiative properties of cirrus and their variations during their life cycleMeasure in cloud and clear sky supersaturation to determine the modification of the water vapor budget of the tropopause region by cirrus cloudsInvestigate the impact of “anthropogenic perturbations” (e.g. heterogeneous IN) on mid latitude cirrus

Implementation of new technologies on HALO

Aims of the HALO ML-CIRRUS Mission


Investigate ice nucleation and cirrus properties in different dynamical forcing regimes / updraft velocities

Study regions for WCB cirrus (red) and HP cirrus (green): Different velocity regimes of cirrus clouds in the vicinity of a warm conveyor belt [from Spichtinger et al., 2005]. Reddish colours indicate stronger vertical updrafts, triggered by the warm conveyor belt, whereas bluish colours indicate low vertical updrafts, associated with the companioning high-pressure system.

Boundary conditions

HALO will operate from OP, in total approx. 50 flight hours are planned; preferred seasons are spring to fall, but all seasons are possible.

Falcon will operate parallel to HALO for specific flight missions; 25 flight hours are planned.

Aviation-Cirrus, Contrails, and Synoptic Cirrus

HALO probes the NAR (45 - 55°N and 10 - 45°W) with active remote sensing of cirrus, dropsondes and in-situ measurements of contrail/cirrus properties. Frontal cirrus and cirrus associated with high pressure systems are explored in "clean" regions over Central and Northern Europe with only moderate pollution by air traffic. Assigned flight hours: 40.


Air traffic control regions for which permissions for measurements and dropsonde release will be requested during ML-CIRRUS.
