Analysis of Visibility at Canadian Speciation Monitoring Sites

摘要

The use of NAPS speciation program data has allowed for an updated assessment of visibility conditions and characterization of spatial and temporal trends at sites across Canada. The addition of source apportionment data along with the reconstruction of light extinction provides an improved and more comprehensive characterization of the factors that influence visual air quality conditions at select sites and can be used to inform air quality management actions targeting visual air quality.
