CASTNET measures ambient concentrations of sulfur and nitrogen species as well as rural ozone concentrations. The network includes 90 sites located throughout the US and Canada. Each site measures weekly concentrations of acidic pollutants, base cations and Cl- using a 3-stage filter pack with a controlled flow rate. Most CASTNET sites also include a temperature controlled shelter and continuous ozone monitoring system.
Results from CASTNET are used to report on geographic patterns and temporal trends in acidic pollutants, deposition and regional ozone concentrations. CASTNET is the only network in the US that provides a consistent, long-term data record of acidic dry deposition fluxes.
