A new study from Florida State University researchers indicates that common satellite imaging technologies have vastly underestimated the number of fires in Florida. Their report, published in collaboration with researchers from the Tall Timbers Research Station and Land Conservancy, challenges well-established beliefs about the nature and frequency of fire in the Sunshine State. While there were more fires than expected, researchers said, strategically prescribed burns throughout the state are proving an effective force against the ravages of wildfire.

The hardworking AERONET (AErosol RObotic NETwork) instrument in Baengyeong, South Korea was having a rough day. Every 15 minutes, the telescope-like device pointed its barrel at the sun to record its light and measure how much was blocked by airborne particles, or aerosols. July 13, 2012 was an overcast day and the light absorbed by the clouds dominated the measurements. But then, just after 1 p.m., the clouds parted, the instrument looked up, and data was collected. Only no one saw it.

A NASA team utilized satellite data to create a map of past volcanic deposits and modeled the risk to nearby towns. They found one town on a potential lava flow path and a second town at risk for mud flows. The results were presented at Monday’s poster session at the American Geophysical Union’s Fall Meeting. The group’s methodology using satellite images can serve as a template for remotely assessing volcano risk, according to the researchers.

California’s persistent drought is forcing grape growers to keep a more-attentive-than-normal eye on their vines, as water shortages and elevated temperatures alter this year’s growing season.

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.
