虽然地表温度（Ts）对土地利用和土地覆被变化引起的生物物理变化的敏感性的迹象相对较好地理解，但其确切幅度以及其幅度如何取决于表征变化大小的尺度仍然难以捉摸。在这项研究中，我们比较了地表温度的敏感性，在地表水和地表水的可用性从三个分析/半分析模型，这是专为小（10-20公里）尺度的变化。结果表明，由于大气反馈，地表温度对生物物理变化的敏感性是尺度相关的。我们的研究结果表明，重要的是要考虑规模和相关的大气反馈时，量化的敏感性表面温度的生物物理变化。
While the signs of the sensitivities of surface temperature (Ts) to land use and land cover change‐induced biophysical changes are relatively well understood, their exact magnitude and how their magnitude depends on the scale characterizing the size of the change remain elusive. In this study, we compare the sensitivities of surface temperature to changes in surface albedo and surface water availability from three analytical/semianalytical models, which are designed for small (10–20 km) scales. Results suggest that the sensitivities of surface temperature to biophysical changes are scale dependent due to atmospheric feedbacks. Our results demonstrate that it is important to consider the scale and the associated atmospheric feedbacks when quantifying the sensitivities of surface temperature to biophysical changes.
