Floods in Turkey
| Title |
Floods in Turkey |
| Description |
The swollen rivers of Western Turkey cut dark blue ribbons across the brilliant green landscape of this false-color Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) image. Starting on January 22, 2004, a rare winter storm [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=11924 ] blanketed Western Turkey with snow. The equivalent of a month?s precipitation fell around Istanbul in just 24 hours. By February 7, when the Aqua [ http://aqua.nasa.gov/ ] satellite acquired this image, most of the snow had melted, filling the rivers that flow into the Aegean Sea. The Meric (Evros) River in the top left corner, and the Menderes River in the bottom third of the image seem particularly full. Only patches of snow, which appear light blue in this image, remain in the higher elevations. The high resolution image above has a resolution of 500 meters per pixel. The image is available in additional resolutions [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2004038-0207/Turkey.A2004038.1110.721 ], including MODIS? maximum resolution of 250 meters per pixel.

Forest Fire in Greece
| Title |
Forest Fire in Greece |
| Description |
South of the city in Thessaloniki in north-central Greece, a large forest fire forced thousands of people to evacuate the southern tip of the Kasandra Peninsula on August 21, 2006. The racing fire forced people to the coastline of the popular tourist area, where many were evacuated by boats. This image of the fire was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite on August 22. The locations where MODIS detected actively burning fire are outlined in red. Smoke spreads east and south over the Aegean Sea. The high-resolution image provided above has a spatial resolution of 250 meters per pixel. The MODIS Rapid Response Team provides twice-daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?AERONET_Thessaloniki/ ] of the area at additional resolutions.

Fires in Southern Europe
| Title |
Fires in Southern Europe |
| Description |
Scores of large fires dotted the Balkan Peninsula on July 25, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this photo-like image. The fires, represented by red dots, pumped out thick plumes of smoke that blanketed the region with haze. A thin, white-gray pall of smoke hangs over the Ionian Sea southwest of Greece, and additional smoke covers the Black Sea in the northeast (visible in the large image). The Aegean Sea to the east of Greece likely also had smoke-filled skies, but sunlight reflecting off the surface of the water masks the haze from view in this image. Aqua MODIS observed additional large fires in Italy on July 24. The fires caused a state of emergency in Macedonia, and Greece put its northern forests under constant watch fearing further fire outbreaks, reported BBC News [ http://news.bbc.co.uk/2/hi/europe/6915157.stm ] on July 25. The fires were fueled by extreme, desiccating heat starting in mid-July. Super-hot air pushed north from Africa and settled over much of southeastern Europe, where temperatures climbed above 40 degrees Celsius (104 Fahrenheit). As many 500 died in the heat in Hungary (north of the area shown here), and the high demand for power caused black-outs in Greece, Kosovo, and Montenegro, said the BBC. The large image provided above is at MODIS' maximum resolution of 250 meters per pixel. The image is available in additional resolutions from the MODIS Rapid Response System.

Fires in the Balkans

Fires in the Balkans |
| Description |
On Tuesday, March 25, 2003, the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite captured this image of widespread fires (red dots) across the Balkans. At lower left is the Adriatic Sea (and Italy), and at bottom right is the Aegean Sea. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at MODIS? maximum spatial resolution of 250 meters. Image courtesy Jeff Schmaltz, MODIS Rapid Response Team, NASA GSFC |

AIRS First Light Data: Eastern Mediterranean, June 14, 2002 |
| Original Caption Released with Image |
Four images of the Mediterranean obtained concurrently on June 14, 2002 from the three instruments that make up the Atmospheric Infrared Sounder experiment system aboard NASA's Aqua spacecraft. The system features thousands of individual channels that observe Earth in the visible, infrared and microwave spectral regions. Each channel has a unique sensitivity to temperature, moisture, surface conditions and clouds. This visible light image from the AIRS instrument shows a band of white clouds extending from the Adriatic Sea over Greece to the Black Sea. The AIRS image (figure 1) at 900 cm-1 (11 micrometers) measures actual surface or cloud top temperatures. In it, land and ocean boundaries are well defined, with land appearing as warmer (darker red) than the ocean. The band of cold high cumulus clouds appears blue, with the darkest blue most likely a large thunderstorm. The 150 gigahertz channel from the Humidity Sounder for Brazil instrument (figure 2) is sensitive to moisture, ice particles and precipitation. The dry land temperature is comparable to the 11 micrometer temperatures, but over ocean this channel measures the temperature of moisture in the mid troposphere. The cold, blue areas off Sicily and in the Aegean Sea represent unusually dry areas over the ocean. There, clouds appear as green filaments--likely areas of precipitation. The 31.4 gigahertz channel from the Advanced Microwave Sounding Unit instrument (figure 3) is not affected by clouds. NASA's Atmospheric Infrared Sounder (AIRS) onboard NASA's Aqua spacecraft, began sending high quality data on June 12, 2002. This "first light" data is exceeding the expectations of scientists, confirming that the AIRS experiment is well on its way to meeting its goals of improving weather forecasting, establishing the connection between severe weather and climate change, determining if the global water cycle is accelerating, and detecting the effects of increased greenhouse gases. The AIRS sounding suite is a tightly integrated remote sensing system that will be used to create global three-dimensional maps of temperature, humidity and clouds in the Earth's atmosphere with unprecedented accuracy. This will lead to better weather forecasts as well as a wealth of data that will be used to study and characterize and eventually predict the global climate. The AIRS system is made up of three of the six Aqua instruments - AIRS itself, which is an infrared sounder with an unprecedented 2378 spectral channels, complemented with a 4-channel visible/near-infrared imaging module, AMSU-A, which is a 15-channel microwave temperature sounder, and HSB, which is a 4-channel microwave humidity sounder. These instruments are carefully aligned with each other and scan the atmosphere in a synchronized way, giving us simultaneous multispectral views of a highly variable target. 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. |
