Extended Data Fig. 5: Comparison of the measured (−)-α-pinene time profiles with the MEGAN model.

a, The sum of the α-pinene emission and the sum of the α-pinene flux calculated with the MEGAN model as a function of time using the temperature data measured from 13 m on the measurement tower and the PAR data measured outside the Biosphere 2. b, Diurnal cycles of the measured concentration of (−)-α-pinene and (+)-α-pinene during pre-drought on doy 280 in addition to the predicted combined emission flux of (−)-α-pinene and (+)-α-pinene. c, Diurnal cycles of the measured concentration of (−)-α-pinene and (+)-α-pinene during severe drought on doy 296 in addition to the predicted combined emission flux of (−)-α-pinene and (+)-α-pinene.
