Data Collections

Data CollectionsEnvironment Canada's scientific research activities generate large volumes of data on myriad subjects, ranging from sea-ice conditions to releases of industrial air pollutants into the environment.

Some departmental data sets, such as those pertaining to weather and climate, contain measurements and observations that date back more than a century. They serve as an important indicator of how our environment is changing.

This section provides links to some of the Department's many data collections, including online databases, archives, inventories, reports, surveys, maps and atlases.
