The National Science Foundation's (NSF) Division of Atmospheric Sciences (ATM) is doing extremely well, according to a recently completed review of two of its grant programs by an outside advisory committee. As a major part of NSF's activities in the physical sciences, ATM is responsible for providing more than $89.3 million annually in support of principal university research, the National Center for Atmospheric Research (NCAR), and the Upper Atmosphere Facilities radar network.The Advisory Committee for Atmospheric Sciences (ACAS) has both external and internal functions. The committee addresses several internal objectives including provision of oversight of program management required by NSF of individual programs within the division; provision of guidance on both shortand long‐range planning including advice on priorities of scientific needs and opportunities; and advice on the impact of ATM research support programs on the atmospheric sciences community.
