down models of air flow, but these do not form the bulk of today’s atmospheric research. Atmospheric observations can come from routine weather observations, special field programs of relatively short duration, long-term research observations, and climate observing systems. The strategies for conducting atmospheric research are determined by such considerations of how the scientific method is applied.
NSF is responsible for the overall health of science and engineering across all disciplines and for ensuring the nation’s supply of scientists, engineers, and science and engineering educators. The Division of Atmospheric Sciences (ATM) supports research to develop new understanding of Earth’s atmosphere and how the Sun impacts it, as illustrated in the organizational chart for the division (Figure 1-1). Over the past six years, ATM has devoted about 30 percent of its budget to supporting the Lower Atmospheric Research Section, 16 percent to the Upper Atmospheric Research Section, 42 percent to the University Corporation for Atmospheric Research and Lower Atmospheric Facilities Oversight Section,
