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

Emissions from Oil Sands MiningDate: 02 03 2012
Using data from OMI, researchers have found that the emission of pollutants from oil sands mining operations in Canada's Alberta Province are comparable to the emissions from a large power plant or a moderately sized city.Read more ...
Extending the Ozone Monitoring RecordDate: 25 02 2012
A new satellite instrument is sending back detailed information about the health of Earth's ozone layer, the atmospheric gas that shields life from harmful levels of the Sun's ultraviolet radiation. The Ozone Mapper and Profiler Suite, or OMPS - one of five new instruments on the Suomi National Polar-orbiting Partnership (NPP) satellite - will add to a record of space-based ozone monitoring that dates back to 1978. OMPS is one of the successors to OMI and part of a long line of ozone monitoring instruments, so it is important to have overlapping flight time. Researchers will use the coming months (perhaps years) to cross-calibrate the instruments and ensure a seamless, standardized record.Read more ...
SO2 Pollution Controls Bring ResultsDate: 02 12 2011
Scientists, regulators, and the electric power industry came together to address a pollution problem, and the result is cleaner air in the United States. The pollutant is sulfur dioxide, a key emission from coal-fired power plants that contributes to the formation of acid rain and to respiratory health problems.Read more ...
2011 Antarctic Ozone MinimumDate: 21 10 2011
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.Read more ...
Study of Unprecedented Arctic Ozone LossDate: 03 10 2011
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.Read more ...
