Lysimeter assessment of the Simplified Two-Source Energy Balance model and eddy covariance system to estimate vineyard evapotranspiration

•Lysimeter measurements were used to assess EC technique and STSEB model in vineyard.•Residual technique was shown appropriate to force the EB closure in our conditions.•Good performance confirms STSEB as an attractive model to estimate ETa in vineyards.•Daily ETa was modeled with average errors of ±0.6 mm d−1.•Error <10% was observed between cumulated ETa estimates and lysimeter data.
