The sensitivity analysis and validation of a SVAT(Soil-vegetation-atmosphere transfer) model(CUPID) are carried out to identify the parameters of CUPID with the largest influence on canopy component average temperatures and temperature profiles.The simulation process and field experimental designs are presented in detail.The results show that the overall uncertainty of the soil temperatures is unstable during growing season
while the uncertainty of canopy temperature stays at about 2%;air temperature and soil water content are the two biggest error-contributors.It is found by evaluation that the trend between simulated and measured temperatures is consistent.
