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

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.

2011 Antarctic Ozone Minimum

Scientists from NASA and the NOAA confirmed today that ozone depletion over the South Pole in 2011 has reached its annual maximum. Researchers used satellites, ground based monitors, and instrumented balloons to observe the hole, finding it to be among the top 10 worst for the breadth and depth of ozone loss in the 26 year record.

Study of Unprecedented Arctic Ozone Loss

A NASA-led study has documented an unprecedented depletion of Earth's protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere.

The study, published online Sunday, Oct. 2, in the journal Nature, finds the amount of ozone destroyed in the Arctic in 2011 was comparable to that seen in some years in the Antarctic, where an ozone "hole" has formed each spring since the mid-1980s.

Pollution in the Great Lakes Region

Fires throughout Ontario, Canada are generating pollution that is showing up in NO2 data from OMI in the Great Lakes region. The fires have also forced thousands of residents to evacuate to other areas in Canada, according to CBC News. About 112 fires have ravaged 81,545 acres so far

Pollution "Butterfly"

Fires raging in central Africa are generating a high amount of pollution that is showing up in NO2 data from OMI, with the ominous shape of a dark red butterfly in the skies over southern part of the Democratic Republic of the Congo and northern Angola.

Pollution from New Mexico, Arizona Fires

OMI has provided a view of nitrogen dioxide levels coming from the fires in New Mexico and Arizona. Detecting nitrogen dioxide is important because it reacts with sunlight to create low-level ozone or smog and poor air quality.
