摘要：精准的蒸散发观测是解释和理解水与能量交换过程及其机理的重要途经,亦可为蒸散发遥感产品验证提供数据支持。基于表面更新理论的高频温度法对蒸散发物理过程的描述,不同于经典的涡动相关法,是一种新兴的蒸散发观测手段,其观测精度媲美涡动相关系统,且高频温度观测系统成本较低(低于波文比系统),在欧美等地获得推广应用。通过梳理高频温度法理论基础与国外近30年的研究进展,结合国内初步观测与研究成果,探讨了高频温度法应用中面临的问题与挑战,为推动国内蒸散发观测方法多源化并从多角度理解蒸散发过程及其机理提供方法支撑。
Evapotranspiration(ET)encompasses water loss through transpiration and evaporation from soil and water surfaces.Accurate observation of ET is essential for comprehending the ET process,and mechanism,as well as water-energy nexus and land-atmosphere feedback.ET serves as a pivotal link between the hydrological cycle and energy processes.In-situ measurements provide fundamental datasets for validating remotely sensed ET products.The surface renewal theory differs from the commonly used eddy covariance method in describing the physical ET process.Unlike the expensive sonic anemometers in the eddy covariance system,the surface renewal method is cost-effective because it uses a fine-diameter thermocouple to record high-frequency air temperature and estimate the sensible heat flux through coherent structures.The surface renewal method for measuring ET,with an accuracy comparable to that of the eddy covariance system,and it has been widely applied for ET measurements in America and Europe.Recognizing the substantial potential of this method,this paper reviews the theory of surface renewal and research advancements in the method made over the past 30 years.Additionally,preliminary studies related to ET measurements in China using the surface renewal method are also presented.By summarizing this progress and exploring the challenges in the application of the surface renewal method,we can enhance our understanding and promote a variety of domestic ET observation methods.
