Intense laser pulses are sent into the atmosphere. The light that is scattered back from distant particles or molecules is collected and analysed as function of time and frequency shift. The distance between lidar system and sensing volume is given by the round-trip time of the laser pulses and speed of light. From frequency shift the wind profile is deduced by means of the Doppler effect.
Head of the department: Dr. Gerhard Ehret
The department LIDAR develops ground-based, airborne and space-borne lidar systems and applies them for active remote sensing of key meteorological parameter and atmospheric trace gases to facilitate research in weather and climate.
Research areas are:
Major instruments developed and operated are:
The Lidar department supports ESA’s Lidar missions in the orbit through airborne demonstrator experiments, feasibility studies, and validation after launch.
