description Located at 1076 m on a hill overlooking the campus of Appalachian State University (Boone, NC) in the heart of the Southern Appalachian Mountains (36.2° N, 81.7° W), the AppalAIR site housing the APP aerosol system is ideally suited for atmospheric measurements. The southeastern U.S. is home to some of the highest aerosol loading, and specifically biogenically derived organic aerosols, in the country. Continuous measurements from an inlet height of 34 m above the surface of aerosol scattering and absorption, particle number concentration, and chemistry as well as trace gas and meteorological measurements began in earnest in June, 2009. Spectral Optical depth (as a member of NASA AERONET) was initiated in July 2010 and a vertically-pointing micro-pulsed lidar was added in June 2011 to retrieve continuous vertical profiles of aerosols and clouds. We have recently acquired an aerosol mass spectrometer and scanning particle mobility particle size and expect these to be operational by fall 2011. The facility is manned by two faculty members from the university, with a lot of help from capable students. Due to the rural, high elevation location, the measurements made from AppalAIR are regionally representative of the southeastern U.S. We are currently collaborating with the NOAA ESRL, NASA AERONET, North Carolina DENR Division of Air Quality, the Mountain Research Initiative, UNC Asheville, and the Community Collaborative Rain, Hail, and Snow Network. We welcome further collaborations with other atmospheric researchers from around the world. Picture of Appalachian State University facility
