Growing season trace gas and environmental measurements at an experimentally-warmed mesic tundra site

These data files contain trace gas concentrations ( ) and environmental measurements from an ITEX mesic tundra experiment. Snow fences were set up at two sites of each replicate to determine the effect of snow depth on soil respiration. Four treatments were sampled with eight replicates: snow-control, snow-warmed, control-control, and control-warmed. PVC collars (20 cm diameter) were placed on the ground from which opaque, static, non-steady state chambers were used to obtain a 25 mL sample in 12-mL pre-evacuated glass vials (Exetainer 739B, Labco Limited, Buckinghamshire, UK). Vials were analyzed using gas chromatography according to methods by Wilson and Humphreys (2010). Environmental measurements (soil moisture, soil temperature, and active layer depth) were taken twice weekly at site adjacent to the collars.
