SGER: Extension of Surface Energy and Water Cycle Flux Measurements Beyond the International H2O Project (IHOP) Intensive Observation Period

这项探索性研究小额赠款（SGER）将监测美国西南部持续的极端干旱的水文气候方面。项目资源将用于在国际水项目的实地阶段结束后继续进行与核心干旱区域的地表能和水交换有关的实地观测。所收集的数据对于监测和了解严重干旱的原因和影响将是非常宝贵的。Drs。布兰肯（科罗拉多大学）和格罗斯曼（科罗拉多研究协会）将通过土壤湿度和温度以及蒸发测量，对地表条件进行量化描述，并将收集到的数据与该地区的其他通量测量相结合。项目完成后，将于2002年5月19日至11月1日在IHOP的“Site 10”进行详细测量。所获得的陆地表面条件数据集在捕捉水文气候演变为干旱条件方面将是无价的，并应有助于改进对干旱发展至关重要的陆地表面过程的建模。该项目得到了ATM的大尺度和中尺度动态气象项目以及EAR的水文科学项目的支持。

This Small Grant for Exploratory Research (SGER) will monitor hydroclimate aspects of the ongoing extreme drought in the U.S. southwest. Project resources will be used to continue field observations related to surface energy and water exchanges in the core drought region, well past the duration of the field-phase of the International H2O Project (IHOP). The collected data will be invaluable for both monitoring and understanding the causes and impact of severe droughts. Drs. Blanken (Univ. of Colorado) and Grossman (Colorado Research Associates) will produce a quantified description of surface conditions by making soil moisture and temperature, and evaporation measurements, and place the collected data in context of other flux measurements in the region. Upon completion of the project, detailed measurements will have been made at IHOP's "Site 10" from May 19 - November 1, 2002. The obtained land-surface condition data set will be invaluable in capturing the hydroclimate evolution into drought conditions, and should facilitate improvements in modeling of land-surface processes that are critical for drought development. This project is being supported by ATM's Large-scale and Mesoscale Dynamic Meteorology Programs, and EAR's Hydrologic Sciences Program.
