Since 1996 the mobile potassium lidar of the IAP Kühlungsborn has measured metal densities and temperatures at various locations from the Antarctic to the Arctic. Between 1996 and 1998 simultaneous observations with our stationary double metal lidar at 54° N have been carried out. This instrument is able to observe two additional metals which can be sodium, calcium, iron or calcium ions. Both instruments have been aligned to the same field of view. Beside the unique possibility to observe meteor trails with high altitude (7.5 m) and time resolution (1 laser pulse) the obtained data also show close correlations between different metals at altitudes above 100 km. Similar correlations with other latitudes are visible when comparing the data with potassium observations at Tenerife (28° N) and Arecibo (18° N). Recent observations of the mobile potassium lidar at Spitsbergen 78° N show that the metal layer is strongly influenced by the presents of icy particles (NLC/PMSE) under the condition of the very cold polar summer mesosphere. During hundreds of hours of observations of NLC and potassium not one event was found where potassium and NLC coexist in the same altitude. On the other side potassium and NLC are frequently observed in two adjacent altitude channels the lidar (200 m).
