Abstract

Global change, space weather, and their possible adverse impacts on human activities are not only of scientific interest, but also of great public concern. Since the Arctic middle and upper atmosphere exhibits significant sensitivity to internal and external perturbations, systematic studies at high latitudes have become a scientific priority.

Several international research programs are being conducted at the Arctic Light Detection and Ranging Observatory for Middle Atmosphere Research (ALOMAR), which was established at Andøya, Norway (69°N, 16°E) in 1994 to perform regular Arctic light detection and ranging (lidar) observations in tandem with other radio and optical instrumentation, as well as with in situ rocket and balloon measurements [von Zahn, 1997].
