What is the purpose of the network?

Acid Gas and Aerosol Network (AGA-Net) provides monthly average concentrations of acid gases and inorganic aerosol composition at ~ 27 sites. The network provides a long-term dataset of monthly speciated measurements of acid gases and aerosols that are used to provide temporal and spatial patterns and trends, and are used in mapping deposition and critical load exceedance of acidity and nutrient nitrogen.

What is measured?

An extension of the DELTA system at the NAMN sites is used to additionally sample gaseous HNO₃, SO₂, HCl and particulate NO₃^-, SO₄^2-, Cl^-, Na⁺, Ca²⁺, Mg²⁺.
