Monitoring of Combined Atmospheric Gases and Particles

The Combined Atmospheric Gases and Particles data sets were collected at regionally representative sites from ground-based monitoring networks in Canada and the USA. The data are from Canadian federal and provincial networks (past and present) and U.S. historical networks (these data are not available elsewhere) and studies from 1982 to the present.

The archive primarily contains measurement data collected by the Air Quality Research Division of Environment and Climate Change Canada and its external collaborators and contributors. Also included is an archive of historical U.S. and Canadian (federal and provincial) air and precipitation data back to the 1970’s.
