Fires in North Korea

Fires in North Korea

14 April 2009

A thick band of haze blew over the Sea of Japan on 10 April 2009. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image the same day. The haze appears as a translucent band of dingy gray. Over northern Japan, the haze blends with opaque white clouds.

Scattered across the landscape of North Korea are numerous red dots. Thesehotspots show where MODIS has detected unusually warm surface temperatures, likely resulting from agricultural fires or wildfires. Although these fires no doubt contribute to the haze, it probably results primarily from urban and industrial pollution farther inland.

The MODIS sensors on NASA’s Terra andAqua satellites provide fire detection data in near-real-time, which geographers have incorporated into a fire alert system. Land managers and conservation groups in Central America receive alerts on their mobile phones or via email when fires are detected in or near parks or other protected areas.
