The 2015 fire season got off to an unusually early start in Canada when blazes broke out in the Northwest Territories, British Columbia, and Alberta in late May. As the season has progressed, the air in western Canada—as well as large swaths of the United States—grew gray and hazy with smoke.
Beginning on June 28, a sharp trough in the jet stream sent a river of smoke streaming south into the United States. By June 29, smoke darkened the skies over much of Saskatchewan, Alberta, Manitoba, North Dakota, South Dakota, Minnesota, and Iowa.
On June 29, 2015, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image of smoke from hundreds of wildfires in western Canada. Read more

The intense bushfires that strike southern Australia in the summer usually attract the most headlines, but the country’s largest and most frequent blazes actually occur in northern Australia in the spring. In fact, in terms of sheer area burned, satellite observations show that over 98 percent of large fires in Australia occur well outside of densely populated southeastern and southwestern parts of the country.
A fire that began burning in Northern Territory on September 10, 2014, offers a prime example of just how expansive fires from this part of the continent can become. After racing through grasslands for just a few weeks, the fire had charred an area about the size of Massachusetts by October 8, 2014.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this sequence of images showing the progression of the fire. Read more

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured this image of farmland near LaCrosse, Washington, on July 24, 2008. The false-color image was assembled using infrared, red, and green wavelengths of light. This combination is useful for observing vegetation and monitoring its health. Areas with the most vigorous crops, grasses, and trees are bright red. Areas where vegetation is drying or dormant are darker shades of brown and gray. Areas with no red are likely fallow or being prepared for seeding. Read more
A combination of lightning and dry forests fueled numerous wildfires in Canada’s Northwest Territories in July 2014. The fires, burning in Canada’s boreal zone, are producing dense smoke. As of July 8, at least 164 blazes had charred more than 425,172 hectares (1,642 square miles), according to the Canadian government. The fires destroyed one home, forced hundreds of people to evacuate, and sent smoke drifting as far south as the continental United States.

High winds propelled a wildfire through parts of Valparaiso, Chile, on April 13, 2014. It quickly became the largest fire in the history of this port city. The fire started in a forested area on April 12 and eventually reached wooden homes built on steep hills around the city. According to news reports, at least 12 people died, 2,000 homes were destroyed, and about 10,000 people evacuated as the fire moved through a section of the historic city.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this image of the fire at 11:10 am local time (14:10 UTC) on April 13. Fire detections are outlined in red in the forest south of the city, which is pale gray. A long plume of smoke stretches northwest over the Pacific Ocean, a clear indication that winds were strong and blowing the flames toward the city. Read more
