The terrain is undulating and the site is located in a clearing with relatively free exposure to exchange of air masses by wind. The site provides data on deposition in support of effect oriented studies (surface water acidification, forest damage, material deterioration etc.). Data for the site are applied for the following monitoring programmes; EMEP, ICP Waters, ICP Forest, ICP Integrated Monitoring, ICP Materials, The Norwegian Air and Precipitation Monitoring Programme, the Norwegian Monitoring Programme on Forest Damage (OPS), and others.

Birkenes station is designed to characterize the composition of air masses advected to Southern Norway by long-range transport. The observation programme covers composition of precipitation (air quality, acid rain), physical, optical and chemical composition of aerosol particles (climate effect, air quality), as well as long and short-lived trace gases (CO2 / CH4 - climate effect; NMHC / VOC - air quality).
