In the heart of Southwest Virginia lie two technologically distinct power plants. One uses traditional coal-burning technology, and the other uses innovative “clean coal”-fired technology. With two plants within miles of one another, this project aims to use NASA Earth observations to monitor and compare the environmental impacts of each.
The Cheyenne Bottoms Wildlife Area is the largest wetland in the interior United States, and is a stopover for 45 percent of the birds who migrate north through the area. A land cover classification map and an estimate of suspended sediment changes will help managers to track the effectiveness of policies aimed at maintaining this critical habitat.
Tropospheric ozone is harmful to humans, trees, crops, and other vegetation. This project focused on providing the U.S. Forest Service with a sustainable tool to enhance its current ozone monitoring practices using NASA remote-sensing data. Data from the Ozone Monitoring Instrument and the Microwave Limb Sounder aboard the Aura mission were used for this project.
Hydrological modeling has the potential to drastically improve water resource management in Yosemite National Park. By combining satellite-derived data, such as precipitation, temperature, land cover and elevation values, it is possible to ascertain and quantify surface water availability at any given time.
Using pre- and post-attack Landsat imagery, 7.2-meter validation plot data, and various modeling strategies, forest stand changes were measured in a subalpine ecosystem at Fraser Experimental Forest in Fraser, Colorado, which resulted from the mountain pine beetle epidemic from 1996 to 2002. This new information will aid local forest management stakeholders and decision-makers, spur ongoing restoration efforts, and assist future research projects.
A team of NASA DEVELOP interns at Langley Research Center used satellite data along with the U.S. Federal Emergency Management Agency’s HAZUS flood model to examine the destruction caused by extreme rainfall events in Duluth, Minnesota, and Thunder Bay, Ontario.
This project was a feasibility study and technology demonstration project that maximized Suomi’s NPP Visible Infrared Imaging Radiometer Suite (VIIRS). The team tested its capability of detecting and estimating gas-flaring events and associated atmospheric pollutants over North Dakota and Texas.
Are Florida’s mangrove ecosystems on the move? Using a combination of hyperspectral and radar imagery combined with field work, the Smithsonian Environmental Research Center, U.S. Geological Survey (USGS) and NASA’s DEVELOP team partnered to track this dynamic ecosystem as it encroaches upon salt marshes in the north.
Due to civil unrest and the agriculture-based economy, Rwanda’s native forest has been reduced to 5 percent of the nation’s territory. As a result, many species have experienced habitat loss, threatening their survival. A 30-mile corridor is being proposed to connect isolated populations to interbreed and conserve biodiversity.
Nobody likes swimming in a lake in the summer around algae or having slimy aquatic plants brush up on their feet. The DEVELOP team at Marshall Space Flight Center worked to help improve methods for controlling aquatic vegetation in North Alabama. Using Landsat 7 ETM+ and vegetation indices, the team created a method to map aquatic vegetation and points of agricultural source pollution.
