At daylight measurements in the UMLT are hindered by the strong solar background. Nowadays lidars reject a part of the background by narrow band spectral filtering where the spectral width is on the order of the Doppler width of the backscattered signal. Spectral filtering alone reduces the background largely but the remaining background is still several orders of magnitude larger compared to night time observations. In recent years we have therefore developed a new type of Doppler resonance lidar, namely a scanning iron lidar. Compared to up-to-date potassium and sodium lidars the iron lidar provides 2-3 orders of magnitude lower background for resonance scattering and additionally performs simultaneously background free observations of aerosols from the stratosphere to the mesosphere. In July 2008 the instrument was installed closed to ALOMAR at 69° N for temperature measurements during the ECOMA campaign. After the campaign the instrument was operated by remote control with very little onsite assistance. The transition in temperature from summer to winter is covered. We will compare these measurements with the temperatures of the former potassium lidar at Spitsbergen (78° N) and the FS-climatologies at 69° N (Lübken JGR 99) and 78° N (Lübken and Müllemann JGR, 2003).
