Ecology

Ecological management is critical for maintaining and repairing ecological systems so the systems reliably supply human needs while conserving and sustaining ecological services and diversity. Satellite observations can provide critical information relevant to the distribution of ecosystems and their resident species. Natural resource managers and scientists use this information to understand patterns of biodiversity, how biodiversity is changing, drivers of changes, and to predict impacts of environmental changes on ecological systems. The Ecological Management Applications area encourages the use of satellite precipitation data from the GPM constellation to analyze and forecast changes that affect ecosystems and to develop effective resource management strategies.

NASA satellites used to predict zebra migrations
Of stars and stripes: NASA satellites used to predict zebra migrations One of the world's longest migrations of zebras occurs in the African nation of Botswana, but predicting when and where zebras will move has not been possible until now. Using NASA rain and vegetation data, researchers can track when and where arid lands begin to green, and for the first time anticipate if zebras will make the trek or, if the animals find poor conditions en route, understand why they will turn back. Covering an area of approximately 8,500 square miles (22,000 square kilometers), Botswana’s Okavango Delta is...
The NPOL radar and a Summer Tanger
By Ellen Gray, NASA Goddard Space Flight Center Original www.nasa.gov Press Release (published 6/7/12) NASA and Nature Conservancy Agreement Supports [no-glossary]Precipitation[/no-glossary] and Migratory Bird Research The NASA NPOL radar is a research grade S-band, scanning dual-polarimetric radar. It underwent a complete antenna system upgrade in 2010 and is one of two fully transportable research-grade S-band systems in the world. It is used to make accurate volumetric measurements of precipitation including rainfall rate, particle size distributions, water contents and precipitation type...
