ASTER data reveals extent Dominican Republic flooding
Tropical Storm Noel pounded the Dominican Republic with heavy rain as it passed over the island on October 28 and October 29, 2007. The rainfall flooded low-lying areas, such as the area shown in this pair of images. The top image was captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) flying onboard NASA’s Terra satellite on November 6, 2007. A comparison of this image with one ASTER took a year earlier reveals how damaging Tropical Storm Noel was to the region.
Floods in Southeastern Mexico
Floods in southern Mexico had started to recede on November 6, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured the top image. The lower image, from October 5, 2007, shows Tabasco, Mexico, before the floods started. Tabasco is a low-lying state, and even under normal circumstances, water figures prominently in the landscape. Water, black in this combination of infrared and visible light, dots the bright green, plant-covered land in the pre-flood image.
