Air quality forecasts see future in space
Date:12/13/2007

data still pose challenges, however, and researchers are trying to find ways to tease out specific information, such as how much of each gas exists at a specific altitude. This is a particularly challenging measurement to make in the air closest to Earths surface, where the information matters most relevant for air quality regulations. More research is needed to determine the value of the current data and to develop improved sensors for future satellites, Pickering says.

The advances in forecasting air quality are happening fast, spurred in part by concern about global warming. At Earth's surface, warmer temperatures can accelerate the reaction between chemicals in the air that form ozone. "The combination of the increase of transported air pollution and the interaction of climate change and air quality really puts a greater premium on satellite imagery for air quality applications," Scheffe says.
