15 October 2009: Fires and Smoke Plumes, North Korea
The featured image shows fires detected by the MYD14 Active fire detection product, overlayed on the related MODIS image. The image shows also vast smoke plumes which reach out eastward into the Sea of Japan. This MODIS image was captured by the sensor onboard the Aqua satellite on the 15th of October.

12 October 2009: Arnica Fire, Yellowstone National Park, Wyoming
The featured image shows the Arnica fire as photographed by astronauts on-board the ISS on the 24th of September 2009. The image shows clearly the extent and magnitude of smoke plumes coming from forest fires, and is especially interesting in comparison with orthorectified MODIS imagery for a sense of scale.

27 September 2009: Fires, smoke and dust - Queensland, Australia
The featured image shows active fires, smoke plumes and the residual dust still in the atmosphere from a recent large dust storm. The image was taken by the Aqua satellite using the MODIS sensor on the 27th of September.

18 September 2009: Burn Scar - Station Fire North of Los Angeles, CA
The Station fire burned in the north suburbs of Los Angeles starting in late August and was not fully contained until the 19th of September. During this long period of time, the fire spread over 650 square kilometers of land. While it was burning, smoke plumes were distinctly visible on MODIS imagery and fires were detected by the MODIS Active Fire algorithm.
The featured image shows the area in a 7-2-1 false color visualization, which clearly distinguishes the burned area (in red) from its surroundings. This type of visualization of MODIS satellite imagery can be utilized to estimate the area of land burned.
