Ice patterns are seen in Baffin Bay above the arctic circle from the Canadian Coast Guard icebreaker Louis S. St-Laurent on July 10, 2008. Weather matters in the Arctic like it does in few other places, but Environment Canada's forecasts for the North have long been hampered by poor data. Now, the end of a five-year program has installed two new Arctic "supersites" in Whitehorse and Iqaluit to give northerners a more accurate sense of some of the country's most extreme weather -- and improve scientific understanding of the entire changing Arctic.
