Carbon Monoxide from Canadian Fires |
| Description |
Fires in central [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13692 ] and western [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13690 ] Canada impacted air quality in late June and early July 2006. Smoke includes carbon monoxide, [ http://en.wikipedia.org/wiki/Carbon_monoxide ] a gas that is toxic in high concentrations. The Measurements of Pollution in the Troposphere (MOPITT) sensor on NASA's Terra [ http://terra.nasa.gov ] satellite measured carbon monoxide between June 29 and July 5, 2006. This image maps the carbon monoxide that accumulated over the area during that period. MOPITT measures carbon monoxide in parts per billion by volume (ppbv). A measurement of 100 ppbv means that out of every billion air molecules in the air column, 100 of them are carbon monoxide. In this image, the colors indicate the carbon monoxide concentrations, ranging from 0 (blue) to 300 (red). These measurements indicate the carbon monoxide concentration at approximately 3 kilometers above the Earth's surface. Accumulations of carbon monoxide in excess of 150 ppbv are widespread, with small areas of concentrations near 300 ppbv. Patches of gray indicate areas where MOPITT could not collect data, likely due to clouds.

Heat Wave in North America
| Title |
Heat Wave in North America |
| Description |
Scorching summer sun, burning pavement, stinging sweat—normal for July. But in July 2006, temperatures climbed above average levels for the previous six years and stayed warm for several days. During mid-July, a heat wave settled over most of the United States, with air temperatures soaring past 100 degrees Fahrenheit (38 Celsius). Land surface temperatures climbed as well, as this image shows. Most of the United States and portions of Canada and Mexico were much warmer than they had been during the same period from 2000 to 2005. Deep red across the Midwest indicates that land surface temperatures were as much as 10 degrees Celsius warmer than the six-year average, and with the exception of the Pacific Northwest and a few other isolated region, the rest of the country was also warmer than average. The heat wave continued past the period shown here, through the end of July. In California alone, the heat killed at least 126 people, reported Reuters on July 29. This image was created from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite between July 12 and July 19, 2006.

Drought on the Great Plains
| Title |
Drought on the Great Plains |
| Description |
Across the Great Plains of the United States and Canada, devastating drought spread across grasslands and croplands in summer 2006. Poor winter snowfall and a blisteringly hot summer [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13742 ] following several years of dry conditions have created a dire situation for many farmers and ranchers across the region. According to a recent article [ http://www.nytimes.com/2006/08/29/us/29drought.html?ex=1157688000&en=13a216546b7d4243&ei=5070 ] on the New York Times Website, many people are comparing the conditions to the Dust Bowl of the 1930s. The widespread drought conditions are obvious in this vegetation anomaly image based on data from the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite. Places where vegetation is healthier or more abundant than average are green, places where vegetation is about the same as average are pale yellow, and places where vegetation is not as healthy or abundant as average are brown. Gray patches show where no data were available, probably because of persistent clouds. One of the most common satellite-based vegetation maps is a scale, or index, of vegetation greenness called the "NDVI," short for Normalized Difference Vegetation Index. This image compares NDVI values from July 28-August 12, 2006, to the average values from 2001-2005. Vegetation was faring worst along the Missouri River through North and South Dakota, but below-average vegetation conditions stretch across parts of Montana, Wyoming, Colorado, northwestern Nebraska, and Minnesota as well. The plains of Canada's Saskatchewan and Manitoba provinces were suffering drought, too. A few small pockets of green in the image reveal where vegetation greenness values observed by MODIS were higher than average: the mountains of north-central Colorado, southeastern Nebraska, and the Red River Valley. The Red River Valley experienced widespread snowfall and heavy rains in the spring of 2006, leading to significant flooding. [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13500 ] The early-season moisture may have helped the vegetation in the area withstand the hot summer. According to the August 29, 2006, update from the U.S. Drought Monitor, [ http://www.drought.unl.edu/dm/monitor.html ] most of the Northern Great Plains, as well as much of Oklahoma and Texas, was still in the midst of drought, with many areas falling into the highest category: exceptional drought.

Heavy Snow in U.S. Midwest
| Title |
Heavy Snow in U.S. Midwest |
| Description |
A severe winter storm hammered the Midwestern United States on December 1, 2006. According to news reports, the storm iced roads, canceled flights, broke tree branches, left more than two million homes and businesses without electricity, and temporarily shut down part of Interstate 40 in central Oklahoma. Several deaths were linked to the storm, including deaths from traffic accidents and carbon monoxide poisoning. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image of the storm's aftermath on December 3, 2006. By the time MODIS took this picture, the storm had moved off to Canada, and skies over the U.S. Midwest had largely cleared. In this image, the lingering snow looks like a giant finger-paint smear of white on a tan background. Streaks of clouds hover in the east, and lighter cloud cover remains in the north. Besides power outages, the storm caused headaches for air travelers, according to The New York Times. Freezing rains followed by snowflakes built up thick ice at Lambert-St. Louis International Airport, forcing the cancellation of hundreds of flights. Besides heavy snow and grounded flights, O'Hare International Airport in Chicago saw the unusual occurrence of a lightning strike to a cargo plane. Although rare, thundersnow [ http://en.wikipedia.org/wiki/Thundersnow ] can mix electrical storm activity with snow rather than rain. A 250-meter-resolution KMZ file [ http://earthobservatory.nasa.gov/Newsroom/NewImages/Images/UnitedStates.A2006337.1710.250m.kmz ] of the snow storm is available for use with Google Earth.

Hurricane Isaac
| Title |
Hurricane Isaac |
| Description |
On September 30, Hurricane Isaac became the fifth hurricane of the 2006 Atlantic hurricane season. Beginning as a tropical depression (area of low air pressure) three days earlier, Isaac formed in the central Atlantic Ocean far from any land. Isaac initially headed northeast on a track towards Bermuda, picking up power to become a hurricane. But Hurricane Isaac never posed a threat to the island, as it veered onto a more northerly track as the storm became more organized and powerful. As of October 2, 2006, Isaac was headed north and slightly east in the general direction of the Canadian Maritime Provinces. However, it was expected to curve off farther east and to avoid coming ashore in Canada. The hurricane was losing power as it traveled north and was downgraded to a tropical storm by midday on October 2. This photo-like image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] on NASA's Terra [ http://terra.nasa.gov/ ] satellite on October 1 2006, at 12:35 p.m. local time (14:35 UTC). Isaac is a small and well-formed—a tight ball of spiraling clouds around a well-defined eye filled with clouds (a "closed" eye). According to the University of Hawaii's Tropical Storm Information Center, Isaac had sustained winds reaching as high as 120 kilometers per hour (75 miles per hour).

Lake Effect Snow in the United States |
| Description |
Like light radiating from the Sun, streamers of snow streak southeast from the Great Lakes in this photo-like image, collected by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite on December 9, 2006. The snow seen here came from two different storms. The broad swath of white extending from the left edge of the image to Lake Michigan was deposited on December 1 by a powerful winter storm [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17480 ] that left thousands without power for many days. The snow on the southeastern side of the Great Lakes, however, fell on December 7 and December 8 as lake-effect snow. Lake-effect snow occurs along the southeastern edge of the Great Lakes when icy wind blows across the lakes from Canada. The wind picks up relatively warm, moist air over the lakes and pushes it over land, where the air is cooler. When the moist air encounters cooler temperatures over land, the water condenses into precipitation, which in this case fell as snow. The signature of lake-effect snow is striking in this image. A field of white lines the southeastern shores of each of the Great Lakes. The strong winds that generated the snow left their imprint in the form of long streamers of snow that extend all the way to the deep brown folds of the Appalachian Mountains along the right edge of the image.Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/ ] of the United States can be viewed on the MODIS Rapid Response web site. The tiny red dots in this image indicate where MODIS detected fires. NASA image courtesy the MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov ] at NASA GSFC. |

Flooding on the Red River
| Title |
Flooding on the Red River |
| Description |
Major flooding swamped the Red River on April 13, 2006, and the National Weather Service issued flood warnings for most communities that lined either side of the river. As the floods swept north into Canada, Winnipeg was bracing for the inundation, expected to peak around April 20. Along the border between the United States and Canada, the Pembina River was also swollen. Flooding at the confluence of the two rivers was nearing its peak when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite took the top image. The Red River spanned several kilometers in North Dakota and Minnesota in contrast to the thin blue line it formed during the same period in 2005 (lower image). The floods were caused by snow melt and rain. For official flood forecasts and warnings, please visit the National Weather Service [ http://www.crh.noaa.gov/ahps2/index.php?wfo=fgf ]. The large images provided above have a resolution of 500 meters per pixel. Daily images [ http://rapidfire.sci.gsfc.nasa.gov/fas/?USA2/2006103 ] are available from the MODIS Rapid Response Team in a variety of resolutions, including MODIS' maximum resolution of 250 meters per pixel.

Flooding on the Red River

Flooding on the Red River |
| Description |
Fast-melting snow caused floods on the Red River of North Dakota and Minnesota during the first and second week of April 2006. The river was bulging with flood water when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image on April 10, 2006. The flood peak had passed Grand Forks, North Dakota, the cement-colored area west of the river along the lower edge of the image, and was flowing north into Canada. The next city to be inundated by the flood shown here was Winnipeg in Manitoba, Canada, beyond the north edge of the image. According to the Canadian Broadcasting Corporation, residents of Winnipeg were preparing for the floods, expected to hit the city by the third week of April. In the top image, the Red River cuts a wide blue swath across dark red farmland. The land most likely has this hue because agricultural fires commonly scorch away stubble, leaving charcoal behind. In this false-color image, the burnt land looks red. A few wispy clouds, pale blue, drift over the flooded region. The lower image shows North Dakota, Minnesota, and Manitoba three weeks before the floods started. At that time, the river blended with the frozen, snow-covered landscape around it. The river is faintly visible in Canada, but is masked by the state boundary in the United States. To see daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?USA2/2006100 ] of the floods, please visit the MODIS Rapid Response Web site.
