It is known from the literature that an error of 1% in Tb may lead to an emissivity error of more than 1%, depending upon the upwelling and downwelling radiative components [ 49 ].
Web27 May 2009 · Temperature sensitivity of soil respiration (often termed as Q 10) is a factor by which soil respiration is multiplied when temperature increases by 10°C [ Davidson et … Web17 Aug 2024 · Typically, temperature declines with elevation, thus elevation gradients have been widely used to assess soil respiration response to temperature. Studies suggest that CO 2 exchange between soil and atmosphere varies along climatic gradients and that the temperature sensitivity (Q10) of SR increases with elevation [ 14, 28 – 30 ].
