Evaluation of transpiration (Tr) predictions for each raining system¹, ‘Syrah’. RMSE, percentage corresponding to systematic error (RMSE_s), randomly distributed error (RMSE_u), index of agreement (d) and the slope and intercept of the regression between observed and predicted were calculated on an hourly basis. The same indexes were calculated for the daily integrated values (Daily_total). Montpellier, 2009

	RMSE	RMSE_s	RMSE_u	d	Slope	Intercept
VSPl	0.33	11 %	89 %	0.94	0.86	0.06
VSPh_s	0.61	26 %	74 %	0.97	0.85	0.22
Total*	0.55	19 %	81 %	0.97	0.86	0.15
Daily _total ^†	40	24 %	76 %	0.92	1.13	−53

*N_total: 269 points. The hourly RMSE units are in mmol m⁻² s⁻¹.

^† N _daily: 15 d. The daily RMSE units are in mol m⁻² d⁻¹.
