The (BAO) has joined up with NERC’s National Centre for Atmospheric Science () as a community observatory under the Atmospheric Monitoring and Observations Facility (AMOF) network – a move which puts it at the heart of national and international level science surrounding vital atmospheric and air quality research.
Established in 2015 as part of the EU Joint Air Quality Initiative (JOAQUIN), BAO is also part of an advanced atmospheric measurement network covering northwest Europe. It has a particular focus on health-relevant metrics, such as particle composition and ultrafine particles (UFPs).
The observatory at the university's Falmer campus is equipped with a suite of measurement instruments and a meteorology station, which collectively enable continuous and detailed observations to be made of tropospheric and stratospheric composition. Continuous ground level measurements include nitrogen dioxide (NO2), sulphur dioxide (SO2), ozone (O3), benzene (C6H6), formaldehyde (HCHO) and nitrous acid (HONO) gases, and the number and mass concentrations of fine and ultrafine particles.
