A light grayish brown haze is sweeping over the ice-covered Hudson Bay from intense fires burning in Yukon Territory and Alaska to the west. The fires have been burning since mid-June, and in the past two weeks, have blanketed much of Alaska and parts of Canada with thick smoke. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired this image on July 7, 2004. The image is available in multiple resolutions.
Smoke from large forest fires in Alaska has made the rounds across several parts of the Northern Hemisphere since the fires began in mid-June 2004. In this scene, smoke is spreading southward along the western arc of the Alaska Range Mountains and the Alaska Peninsula.
