Antarctica — A unique laboratory for atmospheric studies by optical methods
Optical methods of studying the atmosphere are one valuable means of investigating atmospheric behaviour at heights ranging from less than 1 km to several hundred km. Some examples are given of results from various optical experiments carried out at Halley, Antarctica (76oS, 27oW;L=4.2), as is a consideration of the results of some complementary experiments. By combining observations made using different techniques, an improved understanding of atmospheric, ionospheric and magnetospheric processes is obtained.
