Smoke over Davis Strait

Smoke over Davis Strait

Smoke hovered over the Davis Strait and Labrador Sea in mid-June 2012. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image on June 14, 2012. It shows a mixture of smoke and clouds over the icy region between Canada and Greenland.

The smoke likely originated from fires in Labrador. CBC/Radio-Canada reported that smoke from wildfires in the region prompted authorities to consider evacuating nearby communities, and MODIS observed thick smoke plumes on June 13.

Backward trajectories of the smoke calculated through the Hybrid Single Particle Lagrangian Integrated Trajectory Model (HYSPLIT) indicate that smoke traveled northeastward over the Labrador Sea and Davis Strait. “There is strong evidence that Labrador smoke got into the upper troposphere,” said Mike Fromm of the U.S. Naval Research Laboratory, “where it can often last a long time and travel great distances.”

The sea ice along the left edge of this image is tinted blue, probably due to surface melt.
