The Earth’s middle and upper atmosphere is a complex and important region, here the neutral particles are interacting with charged particles, and the region is coupled with the lower atmosphere as well as the magnetosphere. In order to advance our knowledge on the coupling between the neutral atmosphere and the ionosphere greatly, it is essential to measure relevant neutral and ionospheric physical parameters simultaneously. To make these kinds of simultaneous measurements, we have installed a new sodium lidar for temperature observations near the European Incoherent Scatter (EISCAT) radar site at Tromso, Norway (69.6 deg N, 19.2 deg E). Using the lidar, we have conducted first observations during 1-30 October and 13-23 November 2010, and have obtained temperature data of 82 hours. In this presentation, we will report first results of the sodium lidar observations at Tromso.
