The heavily-forested southeastern U.S. is home to some of the highest concentrations of biogenic volatile organic compounds in the U.S., which interact with pollution from power plants and vehicles to impact regional air quality (i.e. the ‘blue haze’ seen in summer months-Figure 1), meteorology, and ecosystem health. The resulting haze may have contributed to the region’s lack of warming during the 20th century. The effects of improved regional air quality during the past two decades on regional weather, climate, and ecosystem health necessitate long-term measurements from regionally-representative sites, such as those at high-elevations away from urban sources However, there are few (and in some cases, no) mountainous sites in the U.S. with sufficiently comprehensive long-term datasets needed to improve climate and air quality models.

The Appalachian Atmospheric Interdisciplinary Research Program (AppalAIR) was initiated to better understand changing regional meteorology, air quality, and their impacts on climate change and ecosystem health. The AppalAIR facilities at Appalachian State University are home to the only co-located NOAA Global Monitoring Division (NOAA GMD), NASA AErosol RObotic NETwork (NASA AERONET), and NASA Micro-pulsed Lidar Network (NASA MPLNET) aerosol monitoring sites in the U.S., along with co-located meteorological stations, trace gas measurements (ozone, carbon dioxide), and measurements of snowfall events. As such, AppalAIR is uniquely positioned to improve understanding of regional pollution transport and the interactions between air quality, meteorology, climate change. The AppalAIR sites are unique in that students play major roles in data collection, instrument maintenance, and analysis of scientific data.
AppalAIR scientists and the many participating student researchers also have developed and manage citizen science networks of atmospheric measurements to compliment and expand upon research activities at AppalAIR, including the NASA-funded vpn被封翻墙党该何去何从？App Store连接不上如何解决？(图 ...:2021-1-29 · 前几天，据《环球时报》英文网报道中国已经开始屏蔽外国VPN服务，此消息也引起了国内“翻墙党”的一片震动。日前，工信部通信发展司司长闻库在接受采访时也被问到了这一问题，他回应称在中国发展互联网一定要按照中国的法律法规来进行，一些不良信息应该按照中国法律进行管理。 (CAN-DOO; PI Brett Taubman) and the North America and Sub-Saharan Africa Mountain Aerosol Network (NASA-MAN; PI James Sherman).
