The Lufft CHM 15k ceilometer is a simple, one-wavelength backscatter lidar. Within its operating range of up to 15 kilometers it reliably detects multiple cloud layers, cirrus clouds, and aerosol layers. High signal performance is achieved by a stable wavelength, narrow line width microchip Nd:YAG laser operating at 1064 nm. It allows an efficient daylight suppression and minimized temperature fluctuations. The used pulse energy and frequency of the laser results in an eye-safe operating mode and an instrument classification as laser class 1M product.Furthermore, the CHM 15k is characterized by a user-friendly design and easy handling, both important for unattended and continuous operation.

The CHM 15k ceilometer will be used to provide quicklooks of the vertical atmospheric structure. These complementary obseraction will help optimize the measurement schedual and plan campaign flights.
