Boundary Layer Soundings and Regional Surface Heat Fluxes in the Southern Great Plains

[j] .北京：北京大学学报（自然科学版）；该奖项为研究自然地表区域尺度的地表热通量（湍流热通量和辐射热通量）提供了三年的资助。这项工作的一个主要目的是找到一种方法，可以推导出比目前可用的测量技术所施加的10米至100米的特征尺度更大的区域的表面通量。有许多原因需要更好地描述这些数量，其中最重要的是需要改进全球气候模式。这项工作将在位于堪萨斯州和俄克拉荷马州边界的南部大平原的DoB ARM/CART站点进行。该场址设备齐全，可能是世界上进行计划中的研究的最佳场址，在今后三年进行研究期间，将有几个重点突出的特别观察期。这一合作将产生极好的协同效应。研究结果对动态气候模拟和水文应用具有重要价值。

Abstract/Brutsaert, 97-08622 Boundary Layer Soundings and Regional Surface Heat Fluxes in the Southern Great P!ains This award provides funding for three years for research to investigate surface heat fluxes (both turbulent and radiative) at regional scales from natural land surfaces. One principal aim of the work is to find ways to allow derivation of surface fluxes over larger areas than the characteristic scales of 10 m to 100 m imposed by currently available measurement technology. Better characterization of these quantities is needed for many reasons, not least of which is the need for improvement of global climate models. The work is to be carried out at the DoB ARM/CART site in the Southern Great Plains at the border between Kansas and Oklahoma. The site is highly instrumented and is probably the best site in the world for the planned research, and several focused special observing periods will occur during the next three years while the research is being carried out. The synergy that will be achieved as a result of this cooperation will be excellent. The results will he of considerable value in dynamic climate modeling and hydrological applications.
