Description: Tropical forests absorb large amounts of atmospheric CO2 through photosynthesis, but elevated temperatures suppress this absorption and promote monoterpene emissions. This dataset contains leaf and ecosystem monoterpene emissions and normalized ratios as a function of leaf and canopy temperature during the 2015/6 El Nino in Manaus, Brazil. Also included are 13C-labeled monoterpene data during leaf photosynthesis under 13CO2. Data was used in the publication, "Monoterpene ‘thermometer’ of tropical forest‐atmosphere response to climate warming." See the below Dataset Reference field for the complete publication citation.
QA/QC: Full QA-QC
Methods Description: Following air sample collection onto thermal desorption tubes, monoterpenes present in rain forest ambient air and leaf enclosure air samples were identified and quantified using thermal desorption gas chromatography mass spectrometry (TD‐GC–MS). See the related publication for detailed data collection and QA/QC methods.
