What will CLARREO Pathfinder do?

The letters in CLARREO stand for the Climate Absolute Radiance and Refractivity Observatory mission. CLARREO Pathfinder will measure the light and energy reflected off the Earth that comes from the Sun and will help to improve the accuracy of climate measurements collected by other satellites. These measurements will help scientists make better predictions of Earth’s future climate. The satellite will also use GPS signals—the same kind you would use to find directions—to measure the temperature of the atmosphere.
