“You see clouds as part of weather every day, but there’s information that we don’t have that’s critical. We can’t tell you, for example, how much water and how much ice exists in the clouds that surround our planet,” said CloudSat’s principal investigator, Graeme Stephens of Colorado State University. “We can’t tell you this very basic information that affects the water cycle and the energy cycle of weather and climate systems.”
