Temporal changes in CWSIh1 and CWSIh2 obtained by replacing the upper or lower limits of the canopy-air temperature difference. The CWSIh1 is the CWSI calculated using the lower limit of the canopy-air temperature difference of the CWSIs and the upper limit of the canopy-air temperature difference of the CWSIt. The CWSIh2 is the CWSI calculated using the upper limit of canopy-air temperature difference of the CWSIs and the lower limit of canopy-air temperature difference of the CWSIt
