Field research missions were carried out during the period 1 June 1976 through 31 July 1976 on a larger and more comprehensive scale than during previous seasons. No seeding was conducted. The scope and quality of the data set collected appear to be unprecedented. Approximately 130 persons representing the National Center for Atmospheric Research (NCAR), the Desert Research Institute (DRI) of the University of Nevada, the National Oceanic and Atmospheric Administration (NOAA), Oregon State University, the South Dakota School of Mines and Technology (SDSM&T), the University of Wisconsin, the University of Wyoming, and the Federal Aviation Administration (FAA), participated in the summer operation. The purpose of this document is to present the research objectives and plans for the 1976 field season, describe the observational systems and networks, summarize the daily research activities, discuss the quality and availability of the observed data, and in summary present highlights and conclusions.
