AB: Between June, 2001 and August 2003 the mobile potassium lidar of the IAP K{\"u}hlungsborn was installed at Spitsbergen, 78$\deg$N. The lidar was in operation during the summer seasons of 2001 and 2003 to observe NLC and temperature at the mesopause region. By adding the data from spring 2002 a complete set of temperatures covering the period from March to October has been obtained. Temperatures below 120 K during mid summer are frequently observed. Wave activities can cause the temperature to drop below 100 K during the coldest period around July 1. During the ROMA campaign 2001 a comparison with temperatures derived by a totally different technique (Falling Spheres) is possible and shows good agreement.
