Noctilucent Clouds are a tracer for the dynamics in the atmosphere at 80 km to 85 km altitude. NLCs are formed in the polar summer mesopause region when and where the temperature is below the frost-point temperature. Occasionally, the clouds reach mid-latitudes, where temperatures are on average above the frost point. We operate a vertical-pointing daylight-capable Rayleigh-Mie-Raman (RMR) temperature lidar and a Doppler RMR lidar with two 25° off-zenith beams at Kühlungsborn/Germany (54°N, 12°E), complemented by the SIMONe meteor radar network. By doing so, we get temporal, vertical and horizontal information about the NLC with a distance of ~40 km between the three fields of view. Results from the first case studies are presented.
