Short summary

Accurately estimating coupling of evapotranspiration (ET) and soil water content (θ) at different depths is key to investigating land–atmosphere interaction. Here we examine whether the model can accurately represent surface θ (θ_s) versus ET coupling and vertically integrated θ (θ_v) versus ET coupling. We find that all models agree with observations that θ_s contains slightly more information with fPET than θ_v. In addition, an ET scheme is crucial for accurately estimating coupling of θ and ET.
