 ==== Ceilometer ====
-Our [[instruments:ceilo:ceilometer|ceilometer CT25K]] is based on the light detecting and ranging (LIDAR) principle: it sends out laser pulses and measures the backscattered light (at 905 nm). From the time delay it derives cloud base height (i.e. the //ceiling// in aviation) up 7.5 km hieght as well as boundary layer structures. We also operate a high-power ceilometer [[instruments:ceilo:ceilometer_jen|CHM15k]] which can detect clouds up to 15 km height. For background information see the [[http://wiki.eg-climet.org/index.php?title=Ceilometer|EG-CLIMET wiki]].

 ==== Cloud Radar ====
-Our scanning [[instruments:mira:mira|cloud radar JOYRAD-35]] is a pulsed Doppler radar which measures profiles of reflectivity, Doppler velocity, Doppler spectral width, and linear depolarization ratio at 35.5 GHz. From these, various macro- and microphysical properties of clouds and precipitation can be derived. In addition, we operate the 94 GHz FMCW cloud radar [[instruments:joyrad94:joyrad94| cloud radar JOYRAD-94]] which can resolve cloud structures down to a resolution of 5 m. For background information see the [[http://wiki.eg-climet.org/index.php?title=Cloud_radar|EG-CLIMET wiki]].

 ==== Doppler Lidar ====
-The [[instruments:wind_lidar|Doppler Lidar]] sends out pulses of light in the near-infrared part of the spectrum. The Doppler shift of the signal backscattered by aerosol can be used to infer line-of-sight wind speed within the boundary layer. Scanning in elevation and azimuth allows derivation of the full wind vector. For background information see the [[http://wiki.eg-climet.org/index.php?title=Doppler_Wind_Lidar|EG-CLIMET wiki]].
