Comparison of combined soil respiration (Rs) model (Logistic-power) with both soil temperature (Ts) (°C) and soil water content (VWC) (m3m−3) as predictors and temperature-only model.

RMSE, MEF, and r2 refer to root mean square error, model efficiency, and determination coefficient of regression, respectively. The values are from fitting functions for time period with measurements of Rs, Ts and VWC.
