On June 23, 2013, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image of wildfire smoke over the North Atlantic Ocean near Newfoundland. The smoke has a yellow-tan or milky gray color compared with brighter white clouds.
Data from other satellites suggests that the smoke originated from wildfires in Canada; it is less likely, but possible, that it came from wildfires in Colorado and other parts of the southwestern United States.
