Graeme Stephens in front of antenna dishesGraeme Stephens, Principal Investigator

- B.S. from the University of Melbourne, Australia, in physics.
- Ph.D. from the University of Melbourne, Australia, in meteorology.

Research Interests:
Dr. Stephens research activities focus on atmospheric radiation and on the application of remote sensing in climate research, with particular emphasis on understanding the role of hydrological processes in climate change. His work has dealt with the derivation of cloud properties from both space borne and aircraft measurements and the application of this information to problems of better understanding the physical processes that define the Earth's atmosphere.

- B.S. from the University of New Mexico, in electrical engineering.
- M.S. from the University of South Florida, in electrical engineering.

Profile Feature:
Students of Shotokan Karate learn to penetrate through an opponent. JPL's Tom Livermore, a first-degree black belt, uses this same technique in the art of managing the CloudSat mission.

Deborah VaneDeborah Vane, Deputy Principal Investigator

- B.S. from the University of Colorado, in physics.

Deborah Vane is the JPL resident representative of the mission principal investigator, facilitates principal investigator communication with JPL management, participates as a member of the CloudSat Science Team, manages the contracts with the co-investigators, participates in mission validation program, and monitors the educational outreach and public outreach programs. Deborah joined JPL after obtaining her bachelor's degree in Physics with Honors at the University of Colorado in 1977, and her first assignment was as a member of the Mars Viking Lander Imaging Team. Since that time, she has participated in several capacities in JPL missions and programs. She managed the proposal team for CloudSat.

Picture of Ron Boain Ron Boain, Project System Engineer

- B.S. from the University of Missouri, in physics.
- M.S. from the University of Missouri, in physics.

Ron Boain has 30 years of aerospace engineering experience at NASA's Jet Propulsion Laboratory. More recently in that period, his career emphasis has been the mission design and system engineering of Earth-orbiting science missions, in particular Topex/Poseidon, Jason-1 and CloudSat. His unique and significant contribution to CloudSat was his vision to fly the CloudSat spacecraft in a tight formation with Calipso, and he was instrumental in every aspect of the mission design to implement this vision. As the Project System Engineer, he has responsibility to ensure that the formation flying objectives are met without undue risk and he ensures that the project systems' actual technical performance meets the requirements.

CloudSat is an international and interagency mission with project management by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Partners include Colorado State University (scientific leadership, science data processing, education outreach), the Canadian Space Agency (radar hardware and scientific contributions), the U.S. Air Force (satellite on-orbit operations control) and the U.S. Department of Energy (scientific contributions). Ball Aerospace & Technologies Corp., Boulder, Colo., designed and built the spacecraft.
