Adjusted and Homogenized Canadian Climate Data

This web site provides adjusted and homogenized climate data for many climatological stations in Canada. These data were created for use in climate research including climate change studies. They incorporate a number of adjustments applied to the original station data to address shifts due to changes in instruments and in observing procedures. Sometimes the observations from several stations were joined to generate a long time series. The adjusted and homogenized data are provided for four climate elements: surface air temperature, precipitation, surface pressure, and surface wind speed.

本网站提供针对加拿大众多气象站点的调整和均质化气候数据。这些数据专为气候研究，包括气候变化研究而创建。为了解决因仪器变化和观测程序变更而导致的偏差，对原始站点数据应用了一系列调整。有时，将多个站点的观测数据合并以生成长时间序列。调整和均质化数据包括以下四个气候要素：地表空气温度、降水量、地表气压和地表风速。
