During the past several years, the President of the United States has made the utilization of solar energy a national goal. The National Science Foundation was given the task to coordinate Federal activities in solar energy research and technology. One of the general objectives of this program is "to provide the research and technology base required for the economic terrestrial application of solar energy; and, to foster "the implementation of practical systems to the state required for commercial utilization." The National Oceanic and Atmospheric Administration, in cooperation with the National Science Foundation, held a Solar Energy Workshop on November 29-30, 1973. The objective of the workshop was to identify the requirements of the solar energy community by means of discussions among specialists in solar radiation technology. A first draft of its recommendations to Working Group 1 appears in Attachment #1.
