AB: Between 2001 and 2003 a potassium lidar was installed near Longyearbyen (78$\deg$N) on the north polar island of Spitsbergen which is part of the archipelago Svalbard. The potassium lidar is capable of detecting noctilucent clouds (NLCs) and of measuring temperatures in the mesopause region, both under daylight conditions. At the same place a series of meteorological rockets (falling spheres) were launched in during the ROMA campaign in 2001 which gave temperatures from the summer mesopause to the stratosphere. The location of the lidar was close to the Sousy-Radar which has frequently observed PMSE throughout the summer periods of 2001 and 2003. We give an overview on the NLC and PMSE measurements and compare the results with temperatures in the same altitude region derived from the meteorological rockets. The NLC and PMSE appearance with height and season is in agreement with the climatological variation of water vapor saturation derived from the temperature measurements.
