These data describe field measurements of soil CO2 flux, soil moisture, and soil temperature for a climate experimental study site in a dry tundra ecosystem near Thule, Greenland. Field measurements were collected in four experimental treatments simulating potential future climate scenarios predicted by the International Panel on Climate Change (IPCC). The four treatments represent: 1) control conditions with no treatments; 2) water addition to simulate greater precipitation; 3) heat addition (heated by 2ºC) to simulate warmer conditions; and 4) both water and heat addition. Field measurements were collected once per week throughout the 2015 summer season. Data presented here represent the mean value of four replicate data collection points for each experimental treatment on each day of collection. The data are arranged as: date, climate treatment type, mean soil CO2 flux (µmol m-2 s-1), flux standard error, mean volumetric soil moisture, moisture standard error, mean soil temperature (ºC), and temperature standard error.
