The Early Canada Environmental Data project is launching a series of new tools and updated webpages to encourage and facilitate research into Canadian climate history.

What’s new?

1) Searchable Reference Database: This database includes references to source materials found in archives across Canada, the United States, and the United Kingdom that can be used for the reconstruction of past climates. In other words, most of the references you will find here are to materials that have regular observations of the weather and often to its broader environmental, social, and economic effects. Sometimes these are instrumental observations (e.g. -10° C, wind from the North), sometimes they are descriptive (cold, windy, squally). Most of the materials are in either English or French. Most of the materials are not available online but require that you visit an archive. The database also includes a separate tab to search our weather datasets. These datasets are from archival materials that have been digitised. We hope to add further datasets in future, so if you have data that you wish to contribute, please let us know.
