Did you ever notice how the air can seem cooler when you enter a forest? Humans aren’t the only living things that sweat to cool off. When trees and plants “sweat,” they cool themselves andcan cool the surrounding air.Through a process called transpiration,water and nutrients are taken up by plant... Read More

The Sun. It inspires songs, warms us, and grows our food. Life on land and in the oceans, the daily weather, and long-term climate patterns happen primarily because of energy we receive from our closest star. Even tiny variations in that energy can affect the workings of our planet’s atmosphere.... Read More

West Nile Virus (WNV) is commonly spread to humans by the bites of Culex sp. mosquitoes. As South Dakota is the U.S. hotspot for WNV, local scientists and public health officials developed a way to use environmental data from NASA satellites to forecast disease risk. These data help inform... Read More

Large accumulations of cyanobacteria (blue-green algae) are toxic and harmful to people and animals. NASA Aqua and Terra satellite data help detect, forecast, and target responses to Harmful Algal Blooms in the Great Lakes and Florida. This information can aid in risk assessment and decision making... Read More

Ozone (O3) in the air we breathe can have detrimental effects on human health and the environment. The U.S. EPA utilized NASA Aura satellite data of North American background ozone levels to guide its updated National Ambient Air Quality Standards. These new standards will enhance public health for... Read More
