Atmospheric deposition monitoring program: concentrations and trends: selected ions in precipitation 2011-2020

Historical data collected through the Alberta Atmospheric Deposition Monitoring Program were evaluated to understand the current state, long-term trends, annual and seasonal variability at select atmospheric deposition stations. Concentrations of ions in precipitation from seven stations distributed throughout the province were evaluated over 2011 to 2020. Concentrations measured were also compared to those measured in other jurisdictions.
