    Measured eddy covariance evapotranspiration (ET) and vapor pressure deficit (VPD) time series collected on 23 May 1997 from a grassland ecosystem used to illustrate the onset and magnitude of the hysteresis. Following Zeppel et al. [], the magnitude of the hysteresis is quantified as the area enveloped by the ET-VPD relation (Ahys). This measure of hysteresis is computationally robust to loop imperfections, and its magnitude includes the effects of the two dimensions characterizing the hysteresis loop. The arrows together with time ticks indicate the progression of the diurnal cycle from sunrise to sunset.

  • Figure 1. (a) Most ESMs exhibit a high bias in atmospheric carbon dioxide (CO2) mole fraction (b) The multimodel mean is biased high from 1946 throughout the remainder of the twentieth century, ending 5.6 ppm above observations in 2005

    (a) Most ESMs exhibit a high bias in atmospheric carbon dioxide (CO2) mole fraction. The predicted atmospheric CO2 mole fraction for the 19 historical simulations shown here ranges from 357 to 405 ppm at the end of the CMIP5 historical period (1850–2005). (b) The multimodel mean is biased high from 1946 throughout the remainder of the twentieth century, ending 5.6 ppm above observations in 2005.
