A high-density network of temperature and precipitation gauges was set up in the foothills of the Canadian Rocky Mountains, southwestern Alberta, from 2005 to 2010. This array of backcountry weather stations covered a range of surface types from prairie farmland to rocky alpine environments, spanning an elevation range from 890 to 2880 m. This paper presents the daily minimum, mean, and maximum temperature data from the study and the associated spatial and vertical temperature structure.
