The datasets and maps are associated with a research study. Annual total (dry + wet) deposition fluxes of nitrogen (nitric acid, nitrate and ammonium) and sulfur (sulfur dioxide and sulfate) were determined at 15 Canadian Air and Precipitation Monitoring Network (CAPMoN) sites from 2000 to 2018. The sites are located in the west coast, prairies, central and southern Ontario and Quebec, eastern Quebec, and Atlantic Canada. Dry deposition fluxes were estimated using the ambient air concentrations and dry deposition velocities of nitrogen and sulfur compounds. Monitored ambient air concentrations are available from CAPMoN’s Air Filter Pack data, and dry deposition velocities were estimated using ECCC’s Global Environmental Multiscale (GEM) model and Moderate Resolution Imaging Spectroradiometer (MODIS) land use data and leaf area index. Monitored wet deposition fluxes were determined using CAPMoN’s Precipitation Chemistry data and precipitation depth. To evaluate whether acidic deposition exceeded critical loads and assess potential ecosystem effects, aquatic and terrestrial critical loads of acidity were estimated using the Steady-State Water Chemistry and Simple Mass Balance models, respectively, and geospatial tools were used to extract the critical loads data surrounding the CAPMoN sites.
