大气环流模型（GCM）的进一步发展将部分取决于地表植被大气传输方案（SVATS）的结合，该方案更准确地代表地球表面的过程。表面特征控制辐射平衡分量的划分，并负责生成中尺度环流模式。然而，SVATS 子模型参数化的一个主要问题是子模型和 GCM 尺度上过程的空间和时间变化。需要对一个区域内多个尺度的通量、水文平衡成分、植被和地形进行详细测量，以便设计适合中尺度和 GCM 网格尺度的聚合方案。为了解决这些问题，能源部的大气辐射测量（ARM）计划于 1991 年和 1992 年开展了合作测量活动（Doran 等人 1992 年，Barnes 等人 1992 年）。我们在这些活动中的目标是测量一系列尺度上的表面通量，并检查通量测量的聚合，以便为我们在中尺度模型和 GCM 中提供表面特征的区域表示。
Further development of general circulation models (GCM) will depend in part on incorporation of surface-vegetation-atmosphere transfer schemes (SVATS) that more accurately represent the processes at the surface of the Earth. Surface characteristics control partitioning of the radiation balance components and can be responsible for generating mesoscale circulation patterns However, a major concern for the parameterization of a SVATS submodel is the spatial and temporal variability of the processes at the submodel and GCM scales. Detailed measurements of fluxes, hydrologic balance components, vegetation and topography are needed over several scales within a region in order to devise aggregating schemes appropriate for mesoscale an GCM grid scales. To address these issues, a cooperative measurement campaign was conducted in 1991 an 1992 by the Atmospheric Radiation Measurement (ARM) Program of the Department of Energy (Doran et al 1992, Barnes et al 1992). Our goals during these campaigns were to measure surface flux over a range of scales and to examine aggregation the flux measurements to provide a regional representation of the surface characteristics for us in mesoscale models and GCMs.
