Who Are NASA's Earth Explorers?
The elementary school student wondering how El Niño will affect tomorrow's weather. The scientist studying connections between ozone and climate change. And the farmer using satellite pictures to keep track of crops. All of these people are Earth Explorers -- they are all curious about the Earth system. This monthly series will introduce you to NASA Earth Explorers, young and old, with many backgrounds and interests.
Nominate an Earth Explorer!
Tell us about the Earth Explorers you know. We're looking for students, teachers, scientists and others who are working with NASA Earth science data and imagery to better understand our home planet. Send your nominations to Dan Stillman: dan_stillman@strategies.org.

Getting dressed for a cold winter day isn't easy. First comes the long-sleeve shirt. Then comes the sweater. On top of that goes the heavy jacket. Don't forget the gloves, earmuffs and hat.Wirelessly controlled instruments that measure the atmosphere will be carried across icy terrain by a moving platform that uses tracks similar to an army tank.

What does air have to do with ice? Derrick explains that the air above the ice can change it. For example, ice takes in the heat from the air. This causes the ice to melt. On the other hand, snow that falls from the air helps make more ice.
