10 Possible Collaborative Studies: Imager Triangulation of airglow structures for 3-D studies Triangulation of auroral structures for 3-D studies Proton content of aurora over and equatorward of Andøya Characteristic energy of precipitating electrons in aurora over and equatorward of Andøya Comparison of optical vs. radar momentum flux observation –Validation of new tool for momentum flux observations at Andøya

11 Possible Collaborative Studies: Radar Current radars (Andøya, NTNU, Kiruna) affected by orographic, auroral and polar vortex shear zone sources. –Andøya vs Kiruna radar Same sides of the polar vortex and auroral oval, but different sides of the mountains. –NTNU vs Andøya radar On same side of the mountains but opposite sides of polar vortex and auroral oval –NTNU vs Kiruna radar Different sides of the mountains, polar vortex and auroral oval Comparing this triad as a function of polar vortex, auroral and ground- level wind strength and orientation will allow the different sources to be quantified. Use correlation of NTNU-Andøya-Kiruna radars to extend the climatology of gravity waves to horizontal scales beyond 200 km.
