摘要

描述
English: Northwestern Canada felt the effects as Alaska continued to burn in late August 2005. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard the Aqua satellite captured this image on August 23, 2005. In this image, a pale gray cloud of smoke several hundred kilometers long sweeps through the Northwest Territories toward the southeast, barely obscuring the view of Great Bear Lake. The smoke dips into the province of Alberta (bottom center) before turning northeast. It changes direction again to head southward over Saskatchewan and Manitoba (bottom right). Clouds—distinct from the smoke because they are pure white—surround the snaking cloud of smoke and block out the view of eastern Canada.
