Data and R Script for "Alpine surface temperature amplification in summer is horizontally heterogeneous at small scales and intensified with wind and sun" by MacDonald et al. (2025)

The files included were used in the analyses for "Alpine surface temperature amplification in summer is horizontally heterogeneous at small scales and intensified with wind and sun" by MacDonald et al. (2025). Data were collected at Cardinal Divide in Whitehorse Wildlands Provincial Park, Alberta, Canada. The data contained in the file "MainWS.csv" were collected by a weather station at Cardinal Divide located at (52.896777, -117.250102). Only free air temperature (°C), wind speed (m/s), and solar radiation (W/m2) were used in analyses; free air temperature was measured using a Hobo temperature sensor (E348-S-THB-M002), with a solar radiation shield (E348-RS3-B); wind speed was measured using a Davis Wind Speed and Direction Smart Sensor (E348-S-WCF-M003); solar radiation was measured using a silicon pyranometer sensor (E348-S-LIB-M003). The sampling frequency was 15 minutes. The data contained in files labeled as " P#T_24HR.csv" or P#O_24HR.csv" were recorded by thermocouple (Perfect Prime TC0520) units using K-type fibreglass coated wires. The data in "rel_point_temp_master.csv" were recorded using an 8-channel thermocouple (Huato S220-T8) with K-type fibreglass coated wires attached to a PVC pole at 0 cm, 10 cm, 25 cm, 50 cm, 75 cm, 100 cm, 150 cm, and 200 cm. The data in the .csv files were used to perform the analyses in the given R script. This analysis is part of Chapter 1 of the MSc thesis of Alexa A.C. MacDonald, being completed at the Applied Conservation Ecology Lab at the University of Alberta, under the supervision of Dr Scott E. Nielsen.
