NASA Launches Two Weather Satellites


“It is important to understand how much water exists in clouds and how they are vertically structured,” Colorado State University’s Graeme Stephens, CloudSat’s lead scientist, said at a pre-launch news conference. “The views of clouds we see today are two-dimensional, so we can’t tell you [that], or what fraction of the moisture produces rain and snow. This is the kind of information that CloudSat attempts to convey.”
