Observation

The Atmospheric Physics Laboratory has conducted ground based observations of the arctic auroral regions for the past 30 years.  We have a network of Fabry-Perot Interferometers (FPIs) situated at Kiruna and Svalbard since the early 1980s.

These state-of-the-art optical instruments provide continual monitoring of the upper atmosphere through the winter months of November to March.  We are able to obtain high temporal and spatial resolution observations of aurora and airglow emissions, giving measurements of winds, temperatures, and gravity waves.  We are also able to study the coupling mechanisms between the dynamics of the Ionosphere and Thermosphere, under control of the magnetosphere.

The concentric rings show the field-of-view of the UCL Svalbard SCANDI, which is overlooked by the 2 fan shapes that represent the scan of the 2 SuperDARN radars. The yellow markers show the FPIs at Kiruna and Sodankylä. The Aurora Borealis, or 'Northern Lights', are a visual example of upper atmospheric phenomena.
