Chiral monoterpenes reveal forest emission mechanisms and drought responses

This data was obtained during the Biosphere 2 - Water and Life Dynamics measurement campaign between September 2019 and December 2019 inside the Biosphere 2 tropical rainforest, Arizona, USA (DOI: 10.1126/science.abj6789). The Biosphere 2 tropical rainforest was subjected to a 4 month drought and rewetting experiment. This data includes mixing ratios of Isoprene, (-)-alpha-pinene, (+)-alpha-pinene, (-)-beta-pinene, (-)-limonene, (+)-limonene, (-)-camphene, (+)-camphene and gamma-terpinene calculated from data measured with a gas chromatograph - mass spectrometer. This data was sampled to see how the atmospheric concentration of compounds changed due to drought and rewetting.
The data also includes the 13C enrichment measurements of chiral monoterpenes and isoprene taken with a gas chromatograph - isotope ratio mass spectrometer and proton reaction mass spectrometer, respectively. The 13C enrichment experiments were conducted on two individual days during the campaign, once during pre-drought and once during the severe drought. This experiment was conducted to see which compounds became enriched in 13C when the atmosphere was exposed to a large amount of 13CO2.
Also included are sorbent tube measurements taken from branch cuvettes attached to Piper sp. and Clitoria fairchildiana plants, and also taken from soil chambers. The purpose of these measurements was to see how the emissions or uptakes of compounds from the plants and soil contributed to the total atmospheric concentration. The sorbent tubes were subsequently thermally desorbed into a gas chromatograph time of flight mass spectrometer.
Also included is the temperature, photosynthetically active radiation, relative humidity, vapour pressure deficit, soil moisture, and photosynthesis rate data
