全球生产低碳能源的努力导致陆上风力涡轮机的空前部署，这意味着风能发电的土地使用发生了重大变化，对当地气候条件和生态系统过程的调节产生了不确定的后果。在这里，我们提出了高分辨率的数据，从风电场收集的运行和闲置期间，显示风电场影响地面气候的几个措施。具体来说，我们发现，运行的风力涡轮机在夜间将空气温度提高了0.18摄氏度，绝对湿度（AH）提高了0.03克（-3），并在整个昼夜周期中增加了空气，表面和土壤温度的变化。此外，涡轮机对空气温度和AH的小气候影响随距离最近的涡轮机的距离而递减。这些对地面微气候的影响，包括土壤温度，对生态地球化学过程和生态系统碳循环，包括土壤碳储量有不确定的影响。因此，需要提高认识，以确定风能的总体碳平衡。
The global drive to produce low-carbon energy has resulted in an unprecedented deployment of onshore wind turbines, representing a significant land use change for wind energy generation with uncertain consequences for local climatic conditions and the regulation of ecosystem processes. Here, we present high-resolution data from a wind farm collected during operational and idle periods that shows the wind farm affected several measures of ground-level climate. Specifically, we discovered that operational wind turbines raised air temperature by 0.18 degrees C and absolute humidity (AH) by 0.03 gm(-3) during the night, and increased the variability in air, surface and soil temperature throughout the diurnal cycle. Further, the microclimatic influence of turbines on air temperature and AH decreased logarithmically with distance from the nearest turbine. These effects on ground-level microclimate, including soil temperature, have uncertain implications for biogeochemical processes and ecosystem carbon cycling, including soil carbon stocks. Consequently, understanding needs to be improved to determine the overall carbon balance of wind energy.
