AB The quality of long-term eddy covariance data was evaluated by calculating the energy balance closure.The study was conducted in a single plot over four different years and crop types (rapeseed, wheat, peas,and rye) included in a rotation scheme governed by rapeseed. Calculations were made separately fora global dataset covering the whole four year/crop period and for each individual dataset belonging toeach year/crop. The analysis was also carried out for the crop growing season (hereafter referred to as themaximum interest period—MIP). An imbalance of 14% was found when using the global dataset. A similarvalue of 13% was also obtained when the study period was limited to the MIP. A marked improvement wasfound in the energy balance closurewhensoil heat flux,GP , was corrected for soil energy storage. With thiscorrection, a 92% and 93% closure emerged when the global dataset and MIP were studied, respectively.In addition, the energy partitioning in the various processes evidenced different results depending onthe selected study period. When the global dataset was considered, sensible heat, H, usually played themain role in the energy partitioning. However, if only the MIP was selected, latent heat, LE, became themain driver dissipating energy while the crop reached full development for this period. The highest LEcontributions to the energy balance were found for rapeseed and rye.
