2-µm Doppler wind lidar
The coherent 2-µm Doppler wind lidar aboard the Falcon F20 research aircraft has been operated for almost two decades and has made significant contributions to numerous national and international field campaigns. Various scientific questions have been addressed.

ALADIN Airborne Demonstrator (A2D)


On 22 August 2018 the European Space Agency (ESA) satellite Aeolus was launched into space, carrying the instrument ALADIN (atmospheric laser Doppler lidar instrument) as its single payload. It is the first European lidar and the world's first ever Doppler wind lidar in space. ALADIN measures one component of the wind vector along the laser's line-of-sight from ground up to altitudes of 30 kilometers.

ALIMA
ALIMA is a powerful iron resonance and Rayleigh lidar for airborne measurements in the middle atmosphere, including the stratosphere, mesosphere and the lower thermosphere. The lidar probes the iron line at 372 nm wavelength to determine atmospheric temperature, wind and iron density within the iron layer, which extends from approximately 70 to 120 km in altitude.

CHARM-F


CHARM-F is an airborne integrated path differential absorption (IPDA) lidar for operation aboard the research aircraft HALO. This unique lidar system is capable of measuring the column concentration below the aircraft of CH4 and CO2 simultaneously. Day and night, all-seasons and all-latitude measurements are possible with this active system. CHARM-F also constitutes an essential component for the validation of MERLIN.

CORAL
CORAL (compact Rayleigh autonomous lidar) is a lidar instrument specifically designed for the investigation of gravity waves in the middle atmosphere. The project’s uniqueness is its fully autonomous operation. For example, the built-in software monitors the weather condition using cloud cameras, in-situ measurements and forecasts. It then decides when to begin with lidar observations, and starts up the system.
