Observing and Modeling Land Surface Effects

9615583格罗斯曼这项研究涉及参与综合观测和建模工作，其中包括为合作大气-地表交换研究(CASE-97)规划和开展1997年实地活动以及随后的数据分析。Case-97将于1997年5月在位于堪萨斯州威奇托东南核桃河分水岭南部三分之二的Argonne边界层设施(ABLF)进行为期四周的试验。该奖项支持的研究的具体目标是：记录晴朗天气行星边界层(PBL)的表面特性和风、温度和湿度PBL廓线的预算方程的日循环；将PBL廓线和深度的日变化与地面过程、云的存在和夹带联系起来；与其他研究人员合作，在数值模式中测试PBL和地面方案；通过将ABLF配置文件与独立观测数据进行比较，以及在有选择地取消CASE-97测量数据时评估预算计算的退化情况，优化ABLF和CASES阵列中规划的长期PBL和地面观测的设计。***

9615583 Grossman This research involves participation in an integrated observational and modeling effort that includes planning and conducting the 1997 field campaign for the Cooperative Atmosphere-Surface Exchange Study (CASES-97) and subsequent data analysis. CASES-97 will be conducted for a four-week period in May, 1997, in the Argonne Boundary Layer Facility (ABLF) located in the southern two-thirds of the Walnut River watershed, southeast of Wichita, Kansas. The specific objectives of the research supported under this award are: Document the diurnal cycle of the fair-weather planetary boundary layer (PBL) in terms of both surface properties and the budget equations of the PBL profiles of wind, temperature and humidity; Relate diurnal variation of PBL profiles and depth to surface processes, the presence of clouds and entrainment; Collaborate with other researchers to test PBL and surface schemes in numerical models; Optimize the design of planned long-term PBL and surface observations in the ABLF and CASES arrays, through comparing ABLF profiles to independent observational data, and through evaluating degradation of budget calculations when CASES-97 measurements are selectively eliminated. ***
