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

The goal of the study is to characterize the relationships between plant-available nitrogen and productivity and to see how these relationships are manifested in hyperspectral signatures. 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).
