If you live in the mid-Atlantic region of the United States you may notice something different in the sky this month. NASA plans to measure the levels of greenhouse gases in the air over the mid-Atlantic region this month via airplane. Researchers are specifically looking to measure the exchange of greenhouse gases that goes on between the air and the vegetation on land.

The campaign, called the Carbon Airborne Flux Experiment will last the month with the goal of giving the researchers involved a better understanding of the way greenhouse gases impact the Earth. In particular they’ll look at the exchange process called flux and gather information to help improve computer models of carbon sinks.
