Title African Dust Reaches Northern Europe
Description On April 18, 2003, a mixture of dust from the Sahara Desert, air pollution, and smoke lingers over the Atlantic Ocean (left). This image shows numerous fires (red dots) burning in the United Kingdom (left of center) and the Republic of Ireland (farther left). A few scattered fires are burning in other parts of the image. This image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite. Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC
Fog over London
Title Fog over London
Description Thick fog surrounded London on the afternoon of December 20, 2006, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image. White fingers of fog creep from the edge of the fog bank into valleys and over rivers, tracing out the contours of the land. The thickest fog is west of London, the cement-grey sprawl across the center of the image. London's primary airport, Heathrow, is located under the fog bank. As a result, many flights out of the airport were canceled, leaving as many as 40,000 travelers stranded, reported the BBC. [ http://news.bbc.co.uk/2/hi/uk_news/6198917.stm ] The fog disrupted travel out of Heathrow on both December 20 and December 21, and was expected to cause additional cancellations on December 22. London was not the only city in the United Kingdom that experienced disruptions because of fog. In the large image, which shows a broader area, patches of thick fog hang over much of the island.

Title Petrol Depot Fire in the United Kingdom
Description Sunday, December 11, 2005, was a day without sun for many Londoners. At about 6 a.m. local time, an explosion rocked a fuel depot in Hertfordshire, approximately 40 kilometers (25 miles) north of London. The ensuing oil fire sent thick clouds of sun-blocking black smoke billowing over London and South England. By 11:50 a.m., when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flew over on NASA's Terra [ http://terra.nasa.gov/ ] satellite, the smoke had fanned south over tens of kilometers. London, normally a large cement-colored circle on the landscape, was not even visible beneath the smoke. Nearly three hours later when Aqua [ http://aqua.nasa.gov/ ] MODIS flew over, the fire was still burning, and the smoke had spread still farther. By December 12 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13281 ], the smoke had thinned to a single plume. The extent of the smoke is easier to see in the false-color images, right, which were created using light from the shortwave and near-infrared part of the electromagnetic spectrum. In these images, the dark smoke stands out clearly against the brilliant green of the plant-covered land. At the source of the smoke, the intense heat of the fire glows in the infrared. According to news reports, the fire was the largest of its kind ever seen in Europe. British health officials advised those living under the smoke plume to remain indoors. The smoke contains small particles, soot, that may cause irritation when inhaled, but no long-term health effects were expected. The smoke also contains gases like carbon monoxide, carbon dioxide, and sulphur dioxide. For more information about the health impacts of the smoke, see the Health Protection Agency [ http://www.hpa.org.uk/explosions/hemel_Q_As.htm ] web site. The large images provided above are at MODIS' maximum resolution of 250 meters per pixel. Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?Europe_2_01/2005345 ] of the region are available from the MODIS Rapid Response Team in a variety of resolutions.

Title Petrol Depot Fire in the United Kingdom
Description The billowing clouds of black smoke that choked southern England on December 11, 2005, had diminished to a single dark plume by December 12. The smoke is coming from a fire at a petrol depot following a series of explosions, the cause of which was still unknown on December 12. The fire was the largest industrial fire in Europe to date. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image at 12:40 p.m. local time on December 12, 2005. The dark plume of smoke that blows southwest from the fire blends with the green and tan of the underlying landscape. It is easiest to see from the shadow it casts on the ground. Skies over the London metropolitan area, the cement-grey area southeast of the fire, are clear, an improvement from December 11 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13280 ] when the smoke entirely obscured the city from view. The smoke contains small particles, soot, and may cause irritation when inhaled. For this reason, British health officials have advised people near the blast to remain indoors. The smoke also contains gases like carbon monoxide, carbon dioxide, and sulphur dioxide. For more information about the health impacts of the smoke, see the Health Protection Agency [ http://www.hpa.org.uk/explosions/hemel_Q_As.htm ] web site. The large image provided above is at MODIS' maximum resolution of 250 meters per pixel. It is available in additional resolutions from the MODIS Rapid Response Team.

Fires in Italy
Title Fires in Italy
Description In Italy and neighboring southern European countries, extreme heat exacerbated dozens of forest fires burning across the country. According to news reports, many of the fires were started by people hoping to lay claim to the degraded land for new construction. This image of Italy was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite on July 24, 2007, and places where the sensor detected actively burning fires are marked in red. Several fires are large enough to spread smoke over the Adriatic Sea. The extreme heat in southern Europe and the devastating flooding in the United Kingdom are linked to an unusually southern position of the jet stream, which is bringing hot air from Africa to southern Europe and causing storms to track across the United Kingdom. Fires are also burning across the Balkans.

Title Smoke Over Northern Europe and the Atlantic
Description Although skies may have been mostly cloud-free over Ireland and the United Kingdom on May 10, 2006, a pall of haze dimmed the day. The white haze drifts from the Atlantic Ocean northwest of Ireland, over the island country, and southeast over the Celtic Sea and the English Channel in this photo-like image taken by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite. The smoke is coming from hundreds of fires [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13539 ] burning in western Russia, most of which are probably agricultural fires. The fires have been burning since late April, and in that time, the smoke has drifted northwest over Scandinavia, the Norwegian Sea, Iceland, and the Atlantic Ocean before curving south to blanket Ireland. Unrelated to the smoke, the ocean southwest of Ireland is brilliant green-blue where a large phytoplankton bloom is growing. Phytoplankton are microscopic plants that grow in the sun-lit surface waters of the ocean. When large colonies develop, the blooms are visible from space by the bright color they lend the normally dark water. The large image provided above has a resolution of 250 meters per pixel. The image is available in additional resolutions [ http://rapidfire.sci.gsfc.nasa.gov/subsets/subsets.php?Europe.2006130.aqua.2km ] from the MODIS Rapid Response Team.

Title AIRS First Light Data: Northern Europe, July 20, 2002
Original Caption Released with Image These images, taken over northern Europe on July 20, 2002, depict a few of the different views of Earth and its atmosphere that are produced by the Atmospheric Infrared Sounder experiment system operating on NASA's Aqua spacecraft. The image in Figure 1 is from an infrared channel from the AIRS instrument that measures the surface temperature in clear areas and cloud top temperatures in cloudy areas. The image reveals very warm conditions in France and a storm off the east coast of the United Kingdom. The image in Figure 2 represents a microwave channel from the Advanced Microwave Sounding Unit instrument that sees through most clouds and observes surface conditions everywhere. The image in Figure 3 is a microwave channel from the Humidity Sounder for Brazil instrument that is very sensitive to humidity and does not see the surface at all, but instead reveals the structure of moisture streams in the troposphere. The infrared and microwave data from the AIRS experiment are integrated to retrieve a single set of temperature, moisture, and cloud values. These three channels represent only a small portion of the 2,400-channel multispectral experiment, whose primary objectives are to improve the accuracy of weather forecasts and to study climate change. The AIRS experiment system also takes pictures of the Earth at four visible and near-infrared wavelengths that can be combined into a color picture. This image shows a swirling low-pressure system over England, clear skies over much of France, and frontal systems in the North Atlantic. Because AIRS is sensitive to different wavelengths than your eye, the colors shown are different from what you would see. For example, plants appear very red to AIRS. There are also subtle color differences in the clouds that relate to their altitude and thickness (compare the white clouds over England with the slightly grey-green ones near Iceland). These images are used in conjunction with other AIRS, AMSU-A, and HSB measurements to get a full 3-D view of the atmosphere. The Atmospheric Infrared Sounder is an instrument onboard NASA's Aqua satellite under the space agency's Earth Observing System. The sounding system is making highly accurate measurements of air temperature, humidity, clouds and surface temperature. Data will be used to better understand weather and climate. It will also be used by the National Weather Service and the National Oceanic and Atmospheric Administration to improve the accuracy of their weather and climate models. The instrument was designed and built by Lockheed Infrared Imaging Systems (recently acquired by British Aerospace) under contract with JPL. The Aqua satellite mission is managed by NASA's Goddard Space Flight Center.

Title AIRS First Light Data: Northern Europe, July 20, 2002
Original Caption Released with Image These images, taken over northern Europe on July 20, 2002, depict a few of the different views of Earth and its atmosphere that are produced by the Atmospheric Infrared Sounder experiment system operating on NASA's Aqua spacecraft. The image in Figure 1 is from an infrared channel from the AIRS instrument that measures the surface temperature in clear areas and cloud top temperatures in cloudy areas. The image reveals very warm conditions in France and a storm off the east coast of the United Kingdom. The image in Figure 2 represents a microwave channel from the Advanced Microwave Sounding Unit instrument that sees through most clouds and observes surface conditions everywhere. The image in Figure 3 is a microwave channel from the Humidity Sounder for Brazil instrument that is very sensitive to humidity and does not see the surface at all, but instead reveals the structure of moisture streams in the troposphere. The infrared and microwave data from the AIRS experiment are integrated to retrieve a single set of temperature, moisture, and cloud values. These three channels represent only a small portion of the 2,400-channel multispectral experiment, whose primary objectives are to improve the accuracy of weather forecasts and to study climate change. The AIRS experiment system also takes pictures of the Earth at four visible and near-infrared wavelengths that can be combined into a color picture. This image shows a swirling low-pressure system over England, clear skies over much of France, and frontal systems in the North Atlantic. Because AIRS is sensitive to different wavelengths than your eye, the colors shown are different from what you would see. For example, plants appear very red to AIRS. There are also subtle color differences in the clouds that relate to their altitude and thickness (compare the white clouds over England with the slightly grey-green ones near Iceland). These images are used in conjunction with other AIRS, AMSU-A, and HSB measurements to get a full 3-D view of the atmosphere. The Atmospheric Infrared Sounder is an instrument onboard NASA's Aqua satellite under the space agency's Earth Observing System. The sounding system is making highly accurate measurements of air temperature, humidity, clouds and surface temperature. Data will be used to better understand weather and climate. It will also be used by the National Weather Service and the National Oceanic and Atmospheric Administration to improve the accuracy of their weather and climate models. The instrument was designed and built by Lockheed Infrared Imaging Systems (recently acquired by British Aerospace) under contract with JPL. The Aqua satellite mission is managed by NASA's Goddard Space Flight Center.
