Floods in Northern Argentina |
| Description |
Late summer rains pounded Northern Argentina in early 2007, triggering the floods shown in this image. The rains started in mid-January, and by March 21, when the top image was taken, the rainfall had caused floods along the Parana and Dulce Rivers and around Laguna Mar Chiquita. The rains were the heaviest seen in Northern Argentina in 45 years, said the Dartmouth Flood Observatory, [ http://www.dartmouth.edu/%7efloods/Archives/2007sum.htm ] and the resulting floods killed 5 and forced 5,000 from their homes. In these images, the floods stretch out over tens of kilometers east of the Parana River. The Dulce River fans across its mouth, where it empties into the Laguna Mar Chiquita. The lower image was taken on January 18, 2007, about the time that the rains started. Like the top image, this image was made with both visible and infrared light so that water is black or dark blue and clouds are pale blue and white. Plant-covered land is green, while bare earth is tan. Agricultural areas are a brighter shade of green than natural vegetation, and the fields give the land a speckled appearance. Similar images are available from the MODIS Rapid Response System [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_NArgentina/2007080 ] on a daily basis.

Floods in Northern Argentina

Floods in Northern Argentina |
| Description |
One of South America's longest rivers, the Parana winds south from its headwaters in central Brazil through Paraguay and Argentina to empty into the Atlantic Ocean near Buenos Aires, Argentina. Near its mouth, the river widens into a multi-stream delta where it joins the Uruguay River to form the broad Rio de la Plata estuary. Small and neatly defined at the height of summer in mid-January, the delta section of the river stretched kilometers across its flood plain in response to unusually heavy late-summer and early-autumn rains by April. The top image, taken on April 3, 2007, shows that not only has the river expanded into a broad black band, but its tributaries are also swollen. Flecks of black south and west of the river show where water covers agricultural fields. These images, both collected by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite, were made with a combination of visible and infrared light to increase the contrast between mud-colored water and land. In these images, water is black or dark blue, and clouds are pale blue and white. Plant-covered land is bright green, and bare earth is tan. In the lower image, taken at the height of the growing season, the agricultural fields are green. By April, the crops had been harvested and the land left bare. The slightly orange color suggests that the fields may have been burned to clear away the stubble. Hugging the west bank of the Parana River, the city of Rosario is a gray-colored spot on the landscape. The floods extend north beyond the top edge of this image, affecting nearly four million hectares (15,000 square miles) and more than 70,000 people in two Argentine states, said the United Nations Office for the Coordination of Humanitarian Affairs (OCHA [ http://www.reliefweb.int/rw/rwb.nsf/db900SID/MCON-6ZX4CN?OpenDocument ]). The flooding was amplified when up to 500 millimeters of rain—more than half the average yearly rainfall—fell over northern Argentina in the span of a few days at the end of March, said OCHA.

Floods in Northern Argentina |
| Description |
Already swollen from late summer rain, Argentina's Paraná River and its tributaries burst their banks under the onslaught of extreme rain during the last week of March 2007. When the clouds cleared on April 3, 2007, the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image of the floods in the Santa Fe and Entre Rios states, where the flood damage was worst. In the center of the image are the two state capitals, Santa Fe and Paraná. The cement-colored cities sit on opposite banks of the river, and both sustained significant damage in the floods. Dark bands of water encroach on the cities in the top image. The lower image, taken on January 13, 2007, before the unusually heavy late-summer rains began, shows the river and its tributaries under dry-season conditions. Both images were made from infrared and visible light to highlight the presence of water, which is black or dark blue in this type of image. Clouds are light blue and white, plant-covered land is green, and bare ground is tan-pink. The variegated green and tan land on either side of the river is agricultural land. In contrasting the two images, it is clear that not only have the wetlands and rivers expanded in the April 3 image, but tiny flecks of black in between the rivers indicate that farmland is flooded as well. According to the United Nations Office for the Coordination of Humanitarian Affairs (OCHA [ http://www.reliefweb.int/rw/rwb.nsf/db900SID/MCON-6ZX4CN?OpenDocument ]), the governor of Santa Fe called March's extreme rainfall "the most radical climatic phenomenon of the last 100 years." Up to 500 millimeters of rain fell over parts of Santa Fe in the span of a week, where the average annual rainfall is 900-1,000 millimeters. The rain left four million hectares (15,000 square miles) flooded, which affected more than 70,000 people, said OCHA. Several cities were flooded, including Santa Fe and Paraná, and as many as 20 were completely isolated. Damage in Paraná was estimated to be over 10 million dollars.

Floods in Northern Argentina

Floods in Northern Argentina |
| Description |
Months of flooding washed even more mud into the wide Rio de la Plata estuary than usual, changing its normally tan waters to a deep chocolate brown. Floods swept across Argentina and Uruguay starting in January and ending in late March 2007, when nearly half the average annual rainfall came down in just a few days. The floods inundated farmland and isolated and damaged cities. Soy farmers may have lost more than two million metric tons of their crop in Santa Fe, the most affected province, reported Bloomberg. [ http://www.bloomberg.com/apps/news?pid=20601086&sid=ajKC2Su30zLs&refer=latin_america ] As the floods drained down the Paraná and Uruguay Rivers, the water swept soil into the rivers. By the time the two rivers converged into the Rio de la Plata, the water was thick with sediment as shown in the top, photo-like image. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the image on April 12, 2007. The lower image, also from Terra MODIS, was taken the previous year, when the sediment in the river was closer to normal levels. The high volume of water draining into the estuary has turned the normally calm, bland surface into multi-shaded streams of mixing water. The high flow is also pushing more sediment out into the hook-shaped Samborombón Bay on the south side of the estuary. Signs of flooding are also evident in the wetlands along the Paraná River. Instead of being deep green as they were in April 2006, the wetlands are almost black under a layer of water. Tan streams of sediment flow from the main channel of the river over the soaked wetlands. Beyond the wetlands and the riverbanks are tiny tan and green squares of farmland. The silver semi-circle on the southern bank of the Rio de la Plata is Argentina's capital, Buenos Aires, and the constellation of cities that surround it. Uruguay's capital, Montevideo, is the silver area along the northern shore of the estuary in the top image (under clouds in the 2006 image).

Fires and Thick Smoke over South America |
| Description |
The skies over the heart of South America were thick with the smoke from thousands of fires on September 9, 2007. In this image from the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ], challenging for scientists to say what the overall effect of smoke on clouds and rainfall is. NASA's Terra [ http://terra.nasa.gov ] and Aqua [ http://aqua.nasa.gov ] satellites each have a MODIS sensor capable of detecting fires and mapping the extent of smoke aerosols on a daily basis. Scientists from around the world are using these data to advance our understanding of how natural and human-caused fires are changing our planet. NASA image created by Jesse Allen, using data provided courtesy of the MODIS Rapid Response [ http://rapidfire.sci.gsfc.nasa.gov/ ] team., satellite, locations where the sensor detected actively burning fires are marked with red dots. The skies are flooded with smoke, which pools along the eastern foothills of the Andes Mountains for thousands of kilometers. (North-to-south this image covers 3,050 kilometers, if we laid it over a map of the central United States, it would spill over the borders into both Canada and the Gulf of Mexico for at least a hundred kilometers in both directions.) Although naturally occurring fires are not uncommon in the drier forests and grasslands of South America, this type of intense, continent-spanning fire activity is almost certainly a product of human activities. Some fires are intentional, set by people to clear forest, savannas, and grasslands for ranching or farming. Other fires occur accidentally from human activities. Landscapes that have been disturbed by logging, fragmentation, or previous accidental fire are more prone to catch fire accidentally. In these situations, planned fires (such as brush clearing fires on already cleared land) can easily get out of control and invade other areas, especially during drought years. The image spans a variety of ecological regions. The top of the scene, including Peru, northern Bolivia, and western Brazil is home to the southernmost portions of the Amazon Rainforest. These wetter forests give way to the south to drier forests and more open woodlands in southern Bolivia, northwestern Paraguay and northern Argentina east of the Andes, this area is called the Chaco. In Uruguay and southern Brazil, the natural vegetation is savannas and grasslands. Even in ecosystems where fires occur naturally (the Chaco, savannas, and grasslands), human activities may change the frequency and intensity of fires. The number and different kinds of plants and animals may change as a result. And in the Amazon, naturally occurring fire was historically very rare, and trees and other plants have no real adaptations to fire. Fires in the rainforest have the potential to completely transform the Southern Amazon forests into a savanna. Fires influence not only the land surface, but the atmosphere as well. Research suggests that the impacts of smoke on the tropical atmosphere vary from place to place, season to season, and year to year. Studies have shown smoke reducing cloudiness over the Amazon itself, but not over the nearby ocean and not every year. The net impact on rainfall is also uncertain. Smoke particles suppress cloud formation by providing an over-abundance of condensation sites for water vapor. The water vapor spreads out over these particles, and it takes the cloud droplets longer to get big enough to fall as rain. The flip side, however, is that the smaller, lighter cloud droplets can rise much higher into the atmosphere, which ultimately invigorates updrafts, intensifies thunderstorms, and produces large hail and heavy rain. The competing effects in different areas and weather conditions make it extremely |

Rare Snow in Buenos Aires, Argentina |
| Description |
For the first time since 1918, snow fell in Buenos Aires, Argentina, late on July 9, 2007, reported the Associated Press. [ http://www.iht.com/articles/ap/2007/07/10/news/Argentina-Historic-Snow.php ] The snow was still there the next morning when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flew over on NASA's Terra [ http://terra.nasa.gov/ ] satellite at 10:55 a.m. local time. This false-color image, made with a combination of infrared and visible light, reveals the snow beneath the clouds that still hang over the coast. In this image, snow is pale turquoise blue, while clouds are lighter blue and white. Not only does the snow blanket Buenos Aires, but it also covers a broad section of the highlands to the west. The snow was short-lived, however. By the time MODIS flew over on the Aqua [ http://aqua.nasa.gov/ ] satellite at 3:10 p.m. local time, both snow and clouds were gone from Buenos Aires, the cement-colored area on the southern bank of the Rio de la Plata in the lower image. The snow had also receded significantly in the higher elevations. The snow fell during a long cold snap that claimed 23 lives and caused an energy crisis, said the Associated Press. True-color, photo-like images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_SArgentina/2007191 ] of the snow in Argentina are available from the MODIS Rapid Response System.

Record Crops in Argentina

Record Crops in Argentina |
| Description |
Despite damaging floods, Argentine farmers were expecting a record harvest in April 2007, reported the United States Department of Agriculture's Foreign Agricultural Service (FAS [ http://www.pecad.fas.usda.gov/wap.cfm# ]). Farmers anticipated a record 45.5 million tons of soybeans and a record 22 million tons of corn when the harvest began at the beginning of the month, said FAS. At the end of March, more than 500 millimeters of rain (about half the average annual rainfall) fell in the period of a few days over parts of the Santa Fe and Entre RÃos provinces, the land spanning the Paraná River. The rain fell on ground already soggy from excess rain, triggering extensive flooding. The floods destroyed between 0.5 and 2 million tons of soy, but caused little damage to the already mature corn crop, said FAS. Both the thriving crops and the flood damage to vegetation are shown in this image. The image shows a vegetation index, a record of plant growth, compiled between March 22 and April 6, 2007, immediately following the damaging rains and floods. The image compares the 2007 vegetation growth to average conditions observed by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite during that same interval between 2000 and 2005. Areas where plants are growing faster or thicker than normal are green, while areas where plant growth has slowed or where plants are less dense than average are brown. The Paraná River is outlined in brown where the overflowing river destroyed vegetation. The land south and west of the river is also dominated by brown, indicating that plants were less healthy than average, probably because of excess rain. This pattern of damage matches the flooding shown in daily snapshot images [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14206 ] of Argentina. Other crop areas in the country are green, showing that growing conditions were good. Even within the flood area, tiny flecks of green show that some fields are still flourishing. Areas where MODIS didn't collect data—probably because of persistent cloud cover—are gray. NASA image created by Jesse Allen, Earth Observatory, using data provided by Inbal Reshef as part of the Global Agricultural Monitoring Project [ http://www.pecad.fas.usda.gov/glam.cfm ] between NASA, USDA's Foreign Agricultural Service (FAS), and the University of Maryland. |
