Dataset and R codes for the article: Boreal conifers maintain carbon uptake with warming despite failure to track optimal temperatures

This data set contains empirical physiological, morphological, and chemical data collected on two dominant conifer species, <em>Picea mariana </em>and <em>Larix laricina</em>, in June and August 2017 at the SPRUCE (Spruce and Peatland Responses Under Changing Environments) experiment that assesses the response of peatland ecosystems to whole-ecosystem warming and elevated atmospheric CO2 concentrations. The SPRUCE experiment is located 40 km north of Grand Rapids, MN, in the USDA Forest Service Marcell Experimental Forest.
