The Department of Atmospheric Science (http://www.uwyo.edu/atsc), one of six in the UW College of Engineering and Applied Science, concentrates principally on research and graduate education. We have 9 faculty members, 25 graduate students, and a staff which is relatively large compared to other departments at UW. The origins of the department can be traced to the college's Natural Resources Research Institute in the 1960s, and its transformation to the Department of Atmospheric Science in the early 1970s. We evolved around faculty interest in observations, developing facilities which now include the King Air research aircraft, the Stratospheric Balloon Facility, the Keck Aerosol Laboratory, Elk Mountain Observatory, and most our most recent addition, the Mobile Air Quality Laboratory. Our King Air has been funded as a national facility under a cooperative agreements between UW and NSF since 1988, and our cloud radar was added in 1999 and cloud lidar system in 2010 to that agreement. Since its origins, the department has broadened in its scientific scope with current strengths in cloud and aerosol physics, stratospheric aerosols and gases, boundary layer meteorology, and mesoscale cloud interactions. Our external funding level is about $4M/year, one of the largest on campus.
