Diurnal plots of 2-hourly averages during the November 2017 warm spell (solid lines) and the 2016 comparison period (dotted lines) for: (a) the climatic variables of incoming shortwave radiation (black lines and circle symbols), air temperature (orange lines and triangle symbols) and vapour pressure deficit (blue lines and square symbols); and (b) the physiological variables of GPP (black lines and circle symbols), ER (orange lines and triangle symbols) and canopy conductance (blue lines and square symbols). Filled symbols indicate variables that are significantly different (P < 0.05) between years for the 2-h period shown.
