Objectives
BETHA-NyÅ aims to investigate how the Arctic Boundary Layer can influence aerosol properties. A detailed knowledge of the atmospheric processes at different scales can help to define the main causes of Arctic Amplification.
Following the SESS recommendations, BETHA-NyÅ will harmonize aerosol measurements at two stations located at different altitudes: Gruvebadet (GVB) atmospheric observatory and Zeppelin (ZEP) station. GVB of ISP-CNR (61 m above sea level) is an atmospheric laboratory dedicated to the chemical and physical monitoring of atmospheric aerosol begun in 2010 and is still ongoing; ZEP (474 m above sea level) is managed by the Norwegian Polar Institute and, compared to stations closer to sea level, is less affected by local anthropogenic aerosol and pollution sources. The differences in concentration levels and seasonal/interannual trends observed at the two sites can help to better understand the impact of local- and long range sources.
