The importance of atmospheric measurements at Alert, Canada



Since 1986 the Atmospheric Environment Service (AES) of Environment Canada has operated an atmospheric chemistry program at Station Alert, which is located at 82°N on the northern tip of Ellesmere Island.

The program provides a detailed record of atmospheric change in the high Arctic that is crucial to both regional and global issues. Plans to reduce the Canadian government's deficit now require Environment Canada to make budgetary cuts and are prompting reevaluation of this and other programs. In light of these circumstances, we would like to take the opportunity to consider the importance of Alert to international atmospheric science.
