Tropical Storm Dianmu

Tropical Storm Dianmu
Tropical Storm Dianmu blew over the East China Sea in early August 2010, traveling slowly toward the Korean Peninsula. On August 10, 2010, the U.S. Navy’s Joint Typhoon Warning Center (JTWC) reported that Dianmu had winds of 55 knots (100 kilometers per hour) with gusts up to 70 knots (130 kilometers per hour). JTWC stated that the storm was roughly 270 nautical miles (500 kilometers) south-southwest of Seoul.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image on August 10. The storm, which sports a distinct eye, stretches primarily north-south, sending spiral clouds hundreds of kilometers southward over the East China Sea. Storm clouds skirt China’s eastern coast.

Smoke from Fires in Canada

Smoke from Fires in Canada
Throughout July 2010, fires burned in the forests of central Canada. The large fires sent plumes of smoke across the country at various times throughout the month. This image shows the cumulative distribution of carbon monoxide, one component of smoke, throughout July.
The highest levels of carbon monoxide are shown in red, while lower levels are yellow. Gray covers regions where the sensor did not collect data during the period. The highest levels of carbon monoxide are in central Canada, over the large fires that burned for much of July. The carbon monoxide extends south and east from central Canada. The image was made with measurements collected by the Measurements of Pollution in the Troposphere (MOPITT) sensor on NASA’s Terra satellite.

Smoke over Western Russia

Smoke over Western Russia
Russia’s wildfires continued to rage on August 9, 2010, producing thick smoke that blanketed much of western Russia. The fire activity and the smoke seemed to be concentrated in two areas, divided by the Volga River. In this true-color image, the most intense fires in the western cluster appear to be south and east of Moscow. Distinct plumes of smoke can be seen rising from several fires immediately southeast of the capital. These fires and others in the region envelop the city in choking smoke, completely obscuring the city from view. Moscow’s approximate location is marked in the image.
East of the Volga River, the fires are concentrated in and near the Ural Mountains. These fires are also visible by the plumes of smoke they are emitting.
On the morning of August 9, 557 wildfires burned in Russia, reported BBC News. Smoke from the fires releases carbon monoxide, fine particles, and ozone-producing chemicals into the atmosphere. Carbon monoxide levels were twice the accepted level in Moscow on August 9, said BBC News.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this image on August 9, 2010. The image is a composite of three separate satellite overpasses. A diagonal line marks the boundary between each successive overpass. The large image is the highest-resolution version of the image, but the image is available in additional resolutions from the MODIS Rapid Response Team.

Carbon Monoxide over Western Russia

Carbon Monoxide over Western Russia
Even as Muscovites choked under a blanket of thick smoke in the first week of August 2010, concentrations of a colorless, odorless gas spiked to dangerous levels. A product of fire and a component of smoke, carbon monoxide is among the pollutants that wildfires spread across much of western Russia. This image, made with data from the Measurements of Pollution in the Troposphere (MOPITT) sensor flying on NASA’s Terra satellite, shows carbon monoxide over western Russia between August 1 and August 8, 2010.
The highest levels of carbon monoxide are shown in red, while lower levels are yellow and orange. Western Russia, including Moscow, sits under a broad area of elevated carbon monoxide. Areas where the sensor did not collect data during the period—probably because of clouds—are gray.
MOPITT measures carbon monoxide in the atmosphere between two and eight kilometers above Earth’s surface. The image shows the composite of those measurements, not carbon monoxide levels near the ground. However, ground measurements of carbon monoxide during the period reached more than six times higher than acceptable levels in Moscow, said news reports.
Carbon monoxide is a dangerous product of fire. The gas can remain in the atmosphere for weeks after being emitted and can therefore travel long distances from the fire that produced it. When it is near the ground where people can breathe it, carbon monoxide poses a health risk. Carbon monoxide binds to red blood cells more easily than oxygen, so it limits the amount of oxygen blood carries through the body. This causes a range of problems from headaches, nausea, and dizziness to cardiovascular problems and confusion. Carbon monoxide is also an ingredient in the production of ground-level ozone, which causes a number of respiratory problems.
