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.

Sulfur dioxide increasing over IndiaDate: 20 12 2013
Emissions of sulfur dioxide from power plants in India increased by more than 60 percent between 2005 and 2012 according to new analysis of data from NASA’s Aura satellite. Led by Zifeng Lu of Argonne National Laboratory, the study was published online on December 5, 2013, in Environmental Science & Technology.Read more ...
Antarctic Ozone Hole in 2013Date: 04 11 2013
According NASA's Ozone Hole Watch team and based upon a combination of ozone column data from OMI and from the Ozone Monitoring and Profiler Suite (OMPS) on the NASA-NOAA Suomi NPP satellite, the ozone hole over Antarctica was slightly smaller in 2013 than the average for recent decades. The combined set of satellite data showed an the average size of the hole in September-October 2013 of 21.0 million square kilometers. The average size since the mid 1990s is 22.5 million square kilometers.Read more ...
Satellites improve air quality monitoring in South AfricaDate: 26 08 2013
Economic development often means an increase of harmful gases into the atmosphere. ESA's GlobEmission project uses satellite data to monitor atmospheric pollution from emissions.
State-of-the-art satellite measurements and computer models are used to calculate the measured air pollutant concentrations back to their origins. This allows for improved emission estimates in terms of spatial consistency, temporal resolution, and for rapid availability.Read more ...
More North American wildfire smoke observed over EuropeDate: 11 07 2013
In the beginning of July 2013, Canadian wildfires have lead to smoke plumes drifting over the Atlantic Ocean towards northern Europe. The wildfires are occurring throughout Canada, from British Columbia to Quebec. These smoke plumes have been detected by ground-based lidar systems in Europe, e.g. in Norway and the Netherlands.Read more ...
