Since the initial thoughts and plans were developed during the 1950's, significant progress has been made in the application of space technology for meteorological uses. New understanding of our atmosphere and useful applications of imagery at both global and local scales have resulted from the program. The papers provided in this report were prepared not only to provide an opportunity to reflect on the accomplishments, but to provide a basis from which the future potentials might be envisioned. The authors and their respective organizations have played very important roles in the meteorological satellite system development and application activities. The papers presented in this report were prepared for presentation at the American Meteorological Society's 62nd Annual Meeting held January 11-15, 1982, in San Antonio, Texas. They comprised the session on Meteorological Satellites - Their Conception, Growth, Accomplishments and Future. The papers are published with the approval of the authors and the American Meteorological Society. A companion session entitled Meteorological Satellites - Past, Present and Future was organized for the American Institute of Aeronautics and Astronautics' 20th Aerospace Sciences Meeting held January 11-14, 1982, in Orlando, Florida. The session contained papers more orientated toward the various meteorological satellite sensor systems. The papers have been published in NASA Conference Publication #2227.

Davis, Universities Space Research Association, Session Recorder and Editor; Melanie A. Cook, Universities Space Research Association, Assistant Editor.
