Daily OMI tropospheric NO2 (air pollution) measurements over The Netherlands and Western Europe

Tropospheric NO2 (air pollution) over The Netherlands and Western Europe (last 24 hours)
The Netherlands and Western Europe air pollution (last 24 hours)

Today's satellite air quality measurements are available around 15:00 hours GMT for Europe. OMI (on the EOS-Aura satellite) passes over Europe around 12:45 hours (GMT) and it takes another 2-2.5 hours before the data are available here. The most recent air quality measurements can be viewed in Google Earth. The TEMIS web site contains a limited archive of air quality and air pollution Google Earth files.

Winds Blow Smoke in California (incl. animation)

Date: 04 11 2007

During the fires in Southern California during the fourth week of October, the air quality in many areas deteriorated to levels that the Environmental Protection Agency categorizes as "unhealthy".

This pair of images shows the location and thickness of smoke on October 24 and 26 combined with arrows showing wind speed and direction. The smoke was observed by the Ozone Monitoring Instrument on NASA's Aura satellite.

Activity at Manda Hararo, Ethiopia

Date: 13 08 2007

In western Afar, Ethiopia, sits a massive volcano complex, roughly 105 kilometers by 25 kilometers. Known as Manda Hararo, the area had not been known for eruptive activity, but in August 2007, satellite, aerial, and ground-based observations showed the volcanic complex coming to life. According to a report from the Smithsonian Institution, an August 16 inspection of the site showed lava flows—including splattering and bubbling lava—from fissures in the complex, as well as sulfur deposits. On August 13, OMI observations detected gaseous emissions of sulfur dioxide.

Smoke Spreading from Greece to Africa

Date: 31 07 2007

Besides laying waste to huge areas of forest, fires burning in Greece in August 2007 released pollutants that traveled across the Mediterranean Sea and into Africa. This image shows aerosols - tiny solid or liquid particles suspended in air - observed by OMI layered on the photo-like composite image.

Driving Ban Lowers Beijing Pollution

Date: 20 05 2007

In an effort to control smog during the 2008 Olympics, Beijing officials planned to institute a number of pollution-curbing measures. One such measure is to limit the number of vehicles on the roads. The Summit of the Forum on China-Africa Cooperation, held in Beijing on November 4-5, 2006, gave officials the opportunity to see just how much pollution would be reduced if traffic were restricted.

Cars, buses, power plants, factories, and homes all pump nitrogen oxides into the atmosphere when they burn fuel at high temperatures. Orbiting overhead once a day, OMI recorded nitrogen dioxide levels. From these measurements, scientists from Harvard University and KNMI estimated that nitrogen oxide emissions were reduced by 40 percent during the restriction period.

Springtime Aerosols over Eastern Asia

Date: 05 05 2007

March 31, 2007, marked opening ceremonies for the first “Green China Day,” established to increase awareness of the need for environmental protection. As reported by ShanghaiDaily.com, however, the ceremony in Beijing saw an unwelcome guest: Gobi Desert dust. Roughly 2,000 kilometers south of the capital city, air quality also suffered, in this case from fires in Southeast Asia.

Mount Etna's SO2 cloud observed above Greece

Date: 01 05 2007

On April 29, 2007 Europe's most active volcano, Mount Etna, has erupted on the southern Italian island of Sicily. Sulfur dioxide (SO2) in this cloud is observed by OMI a day later above Greece. Backward trajectory analyses confirms that the SO2 cloud over Greece comes from mount Etna.

Dust Dampens Hurricane Formation

Date: 18 04 2007

After 2005’s record hurricane season, Caribbean, Gulf Coast, and East Coast residents braced for more destruction in 2006, but the devastating storms never came.

Why the difference between 2005 and 2006? William Lau of NASA GSFC and Kyu-Myong Kim of University of Maryland-Baltimore County think the answer comes from the Sahara, namely dust. Using dust observations collected by OMI, they found that the Sahara sent an unusually large amount of dust over the Atlantic during the 2006 hurricane season. The researchers don’t yet know how great a part dust played in derailing hurricane formation in 2006, but they hope their work will fuel more studies.

Satellite observations of air quality, climate and volcanic eruptions

Date: 15 03 2007

Satellite observations of atmospheric constituents have many applications in the area of climate research, air quality monitoring and security. Here, we will focus on the satellite observations of two important trace gases, NO2 and SO2. Applications are air quality monitoring and support to aviation control.
