Lake Sakakawea and Lake Mead Water Resources and Disasters

Current regional and global scale hydrological models, such as the Coupled Routing and Excess STorage (CREST) model, do not take into account the release and storage of water by man-made dams. These models make gross assumptions about dam operation, impairing their accuracy and utility. In many less economically developed areas of the world, it is not possible to acquire information on the timing and extent of water release in dammed regions.

NASA: A Look Back at a Decade of Fires

NASA's latest Earth-observing satellite, the NPOESS Preparatory Project (NPP), is scheduled to launch from Vandenberg Air Force Base on Oct. 28 to extend key environmental data records established by an earlier generation of NASA satellites. To mark the launch, they are looking back at one of the scientific legacies NPP will build upon: the global fire data record.

Dust and Pollution Rise Before the Monsoon

In the days and weeks before the monsoon, heat builds over India. Hot air rises over the baked earth and westerly winds rush in to fill the void, bringing dust-laden air from the deserts of southwest Asia and the Arabian Peninsula. Through April, May, and June, as monsoon conditions build, the air over the Ganges River plain grows thick with dust, smoke, and haze. Air quality over India is at its worst at this time of year.

Connecting Environmental Observations with Cholera Outbreaks in Bangladesh

Taking a global view, public health issues and the environment are intimately linked. As an example, research has demonstrated that cholera epidemics occur seasonally in Bangladesh, with peak outbreaks happening twice a year. This bimodal outbreak pattern closely follows the times when large monsoon events are frequent (spring and fall).

Texas Drought Disaster

By July 2011, Texas and New Mexico had completed the driest six-month period on record. Average rain between January and June was more than eight inches (203 millimeters) below average in Texas and 3.5 inches (89 millimeters) below average in New Mexico. Record warm temperatures also persisted in Texas between April and June. The lack of rain and the warm temperatures added up to exceptional drought.
