The temperature dependance of soil respiration has most commonly been addressed using surface flux data, despite the fact that surface flux measurements implicate CO 2 transport and storage effects that may preclude robust assessments of the temperature dependence of soil respiration. Here we examine whether soil respiration might be assessed using soil profile CO 2 production inferred from soil CO 2 concentration profiles. Over the 9‐month study period, we observed marked similarities in the temperature response of CO 2 production across four study sites of contrasting vegetation cover and land use.
