Fires Across Northern South America |
| Description |
In eastern Columbia (left) and northern Venezuela (right), a vast stretch of plains called the Llanos rests at the eastern foothills of the Andes Mountains. The Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite detected numerous fires (red dots) scattered across the region, even in wetland areas between two of the Llanos? majors rivers: the Apure (running from center toward the right of the image) and the Meta (flowing northeast from bottom left). Where the Meta leaves the Columbia-Venezuela border, it is joined by the Atabapo River and becomes the Orinoco, which flows out to meet the Atlantic. In the high-resolution imagery, dark purplish-brown burn scars are apparent against the green vegetation of the prairies. At bottom right, the grasses of the llanos give way to the upper reaches of the Amazon Rainforest. This image was captured December 12, 2002.

Fires Across Northern South America |
| Description |
The fires currently burning across northern South America are producing a significant amount of pollution, as indicated by enhanced levels of carbon monoxide in the region. This false-color image shows the concentrations of carbon monoxide (CO) at an altitude of roughly 3 km (700 millibars) in the atmosphere. The data were taken by the Measurements Of Pollution In The Troposphere (MOPITT) instrument aboard NASA's Terra satellite for the period February 24-March 4, 2003. The colors represent the mixing ratios of carbon monoxide in the air, given in parts per billion by volume. The large grey areas in the center of the image show where no data were collected, either due to persistent cloud cover or gaps between satellite viewing swaths. The regions of high carbon monoxide correlate well with observations of the source fires [ http://earthobservatory.nasa.gov/NaturalHazards/shownh.php3?img_id=5633 ] by the Moderate Resolution Imaging Spectroradiometer (MODIS). Carbon monoxide is produced as a result of incomplete combustion during burning processes, and is important due to its impact on chemistry in the lower atmosphere. It is a good indicator of atmospheric pollution, and its presence adversely affects the atmosphere's ability to cleanse itself. Because carbon monoxide is persistent for several weeks, it clearly shows the propagation of pollution plumes from the region of the fires over Columbia and Venezuela westward out into the atmosphere over the Pacific Ocean. The high levels of carbon monoxide in the right of the image over the Atlantic Ocean result from pollution plumes that have traversed the Atlantic from the fires that are currently burning in western Africa [ http://earthobservatory.nasa.gov/NaturalHazards/shownh.php3?img_id=5400 ].

In northern South America, fires (red dots) continue to cover a wide area of Columbia (far left) and Venezuela (center and right). This image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on March 20, 2003, shows fires concentrated heavily east of keyhole-shaped Lake Maracaibo. A thick cloud of smoke hangs over the country. 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 |

Fires in Northern South America |
| Description |
Across the grassy plains, known as the "Llanos," that stretch across Venezuela and Columbia in northern South America, numerous fires (yellow) were detected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite on February 1, 2004. The area supports ranching and other agriculture, and many of these fires are probably intentional fires set by people for land management purposes. Though not necessarily hazardous, such large-scale burning can have a strong impact on weather, climate, human health, and natural resources. At bottom left, a pall of smoke hangs over the area, and a few scattered fires in the heart of the forests (deep green areas at right) could be related to deforestation.

| Description |
February is typically the dry season in northern Venezuela, but not in 2005. Torrential rains brought deadly floods to the country's coastal provinces, including the capital, Caracas. In this Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) image, blue smudges along the coast show flooding in the Falcon Province. In these false-color images, clear water is black, while muddy water is blue. Clouds are white and pale blue, and vegetation is green. When this image was acquired by NASA's Terra [ http://terra.nasa.gov/ ] satellite on February 14, up to 25,000 people had been affected by floods throughout the country. NASA image credited by Jesse Allen, Earth Observatory, using data obtained from the MODIS Rapid Response team. |

Flooding in Columbia and Venezeula |
| Description |
Unseasonable torrential rains drenched northern South America in February 2005. By February 17, at least 55 had died in floods and mudslides in the mountains of northeastern Colombia, and dozens more had been killed across the border in Venezuela. On February 11, the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite detected high water levels on rivers southwest of Lake Maracaibo. The swollen, sediment-laden rivers form a wide blue smudge across the bright green vegetation in the top false-color image. By contrast, more clearly defined river channels were filled with clear, darker water on January 27. In both images, clouds are white and pale blue, while bare earth is pink.

Flooding in Columbia and Venezeula |
| Description |
Though water levels have subsided since mid-February, the Escalante River of southwestern Venezuela and northeastern Colombia was still flooded on February 26, 2005. The floods along this river and others were triggered by days of heavy rain early in February, and resulted in nearly 100 deaths and left thousands homeless throughout both countries. In this image, taken by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite, the muddy flood water is light blue. The river covers a broader area than it did on January 27, 2005. In both images, clouds are white and turquoise, plant-covered land is bright green, and deep, clear water is black. Further evidence of flooding can be seen in Lake Maracaibo in the center of the image. Flood water carries dirt into the rivers that empty into the lake. The sediment entering the lake reflects light, which makes the water appear a lighter shade of blue in satellite imagery. While sediment is present in the southwest corner of the lake on January 27, the sediment plume is much brighter and larger on February 26. On both dates, green swirls of duck weed [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12404 ] float on the surface of the lake. NASA image created by Jesse Allen, Earth Observatory, using data obtained from the MODIS Rapid Response team and the Goddard Land Processes DAAC. |
