Adjusted and Homogenized Canadian Climate Data – Daily Temperature and Precipitation (AHCCD – daily T&P)

The data consist of homogenized daily maximum, minimum and mean surface air temperatures for more than 330 locations in Canada; adjusted daily rainfall, snowfall and total precipitation for more than 460 locations. The data are given for the entire period of observation. Please refer to the papers below for detailed information regarding the procedures for homogenization and adjustment.
