Statistical information from t-test that was performed on the acquired data from the ¹³C-labelled atmospheric samples

DoF is the degrees of freedom and n is the number of samples. PP refers to the samples taken before the ¹³CO₂ labelling (pre-pulse), 1st and 2nd pulse refer to the first and second ¹³CO₂ pulses, respectively, and Post 1st pulse day 1 and Post 1st pulse day 2 refer to the days immediately following the day of the ¹³CO₂ pulses. a, All monoterpenes. b, The different methods of integrating (−)-α-pinene (Extended Data Fig. 7e). DoF is the degrees of freedom and n is the number of samples. PP refers to the samples taken before the ¹³CO₂ labelling (pre-pulse) and 1st and 2nd phases refer to the first and second ¹³CO₂ pulses, respectively.
