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.

Antarctic Ozone Hole in 2013

Date: 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.

Satellites improve air quality monitoring in South Africa

Date: 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.

More North American wildfire smoke observed over Europe

Date: 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.

Smoke from Colorado wildfires reaches Europe

Date: 28 06 2013

On 25 June 2013, smoke from the large wildfires in Colorado (USA) reached Europe. This was seen in the OMI and GOME-2 aerosol images.

The smoke originated from large wildfires in Colorado, in the Rio Grande National Forest around West Fork. The wildfires started on 5 June and were caused by lightning strikes. The main burning material are the many dead trees killed by infestation with the mountain pine beetle. In combination with drought and, from 20 June onwards, strong surface winds (up to 50 mph), this resulted in raging fires. The excessive heat of the fires also caused pyrocumulus clouds. The meteorological conditions caused the smoke to be lifted rapidly to high altitudes (13 km according to Calipso lidar measurements). At high altitudes the smoke was transported to Europe.
