Environment and Climate Change Canada

Short-duration rainfall intensity-duration-frequency IDF statistics in the form of tables and graphs with accompanying documentation for 549 locations across Canada. These files can be downloaded for each province territory or for all of Canada.

Station Catalogue (WMO Volume A Report - Canada) lists all Canadian surface and upper air stations providing synoptic meteorological reports, their operational activities and essential detailed information.

This global dataset contains monthly, seasonal and annual statistics mean and maximum of significant wave height Hs that were produced using a statistical modelling approach and the 6-hourly sea level pressure SLP fields simulated by 20 global climate models participated in the Coupled...

This daily forecast describes the ice edge using latitude and longitude coordinates, the total ice concentration, the predominant ice stage of development and the concentration of the oldest ice type. Warnings are issued as appropriate. The forecasts are valid from the time of issue until the end...

Regional ice charts show the analysis of ice conditions for a given region valid on Mondays. They are based on an analysis and integration of data from: satellite imagery, weather and oceanographic information, visual observations from ship and aircraft. Satellite imagery is collected over a few...

A database of verified tornado occurrences across Canada has been created covering the 30-year period from 1980 to 2009. The tornado data have undergone a number of quality control checks and represent the most current knowledge of past tornado events over the period. However, updates may be made...

Survey points is a point feature class containing transects and observations completed in 2011.

This file includes the spatial boundaries for the Pacific Great Blue Heron Potential Area of Occupancy for its entire Canadian range. The Potential Area of Occupancy is a simple model that highlights the heron's preferred forest habitat at a high level. Potential Area of Occupancy...
