9318896 Wood This proposal is a collaborative effort between Dr. Ann-Henderson- Sellers (Macquarie University), Dr. Dennis P. Lettenmaier (University of Washington), and Dr. Eric F. Wood (Princeton University) The goal is to determine the relative performance of land surface hydrology representations in general circulation models (GCMs) used for climate simulation and numerical weather prediction in terms of their ability to characterize energy fluxes at the land surface and the surface water budget. The proposal has three primary objectives: 1) to evaluate the ability of selected landsurface hydrology models to reproduce measured surface energy and water fluxes using data from a range of spatial scales; 2) To determine how best to combine and extend surface observations, remote sensing, meteorological analyses to validate land surface parameterizations GCMs; 3) To evaluate the ability of selected land surface hydrology models used in GCMs to predict land surface fluxes of water and energy at the scale of global atmospheric models. A suite of models would be evaluated on a hierarchy of validation schemes. The models are 1) the variable infiltration capacity (VIC) model developed by Wood, Lettenmaier, and colleagues; 2) SECHIBA, the land surface model of the LMD (CNRS, Paris) GCM; 3) The ECMWF land surface parameterization; 4) a simplified version of SiB; and 5) BATS. The validation sites and data sets will be: 1) FIFE, a 225 Km2 region of native grassland in the central U.S., and 2) A portion of the Arkansas River basin which includes at least part of DOE's ARM (Atmospheric Radiation Monitoring) Southern Great Plains CART site. A major focus will be to use satellite remotely sensed measurements of land surface fluxes and surface measurements to obtain large-area validation data for evapotranspiration and surface soil moisture. ***

9318896伍德这项提案是安·亨德森博士（Macquarie University），丹尼斯·P·莱特迈尔博士（华盛顿大学）和埃里克·F·伍德（Eric F. Wood）博士（普林斯顿大学）之间的合作努力地表水预算。 该提案具有三个主要目标：1）评估选定的地表水文学模型使用来自一系列空间尺度的数据重现测得的表面能量和水通量的能力； 2）确定如何最好地结合和扩展表面观测，遥感，气象分析以验证陆地表面参数化GCM； 3）评估在全球大气模型的尺度上，GCM中使用的选定土地表面水文模型预测水和能量的土地表面通量的能力。 将在验证方案的层次结构上评估一组模型。 模型是1）木材，Lettenmaier和同事开发的可变渗透能力（VIC）模型； 2）SECHIBA，LMD（CNRS，Paris）GCM的陆地表面模型； 3）ECMWF土地表面参数化； 4）SIB的简化版本； 5）蝙蝠。 验证地点和数据集将是：1）Fife，美国中部的225 km2本地草原地区，以及2）阿肯色河盆地的一部分，其中包括Doe Arm（大气辐射监测）南部大平原推车网站的至少一部分。 主要重点是使用卫星对土地表面通量和表面测量的测量值，以获取大区域验证数据以进行蒸散和表面土壤水分。 ***
