Special Studies

The Special Studies presented on this site are special measurement campaigns (with durations of several weeks to several years) carried out by the Air Quality Research Division of Environment Canada and its government, university and industry collaborators.

The Special Studies data sets consist of air and/or precipitation chemistry data collected at high temporal and/or spatial resolution for the purpose of characterizing chemical concentrations and processes in the atmosphere.

The Special Studies data files made available for download were chosen because of their high potential applicability to current and future atmospheric research.
