A Watershed-Scale Hydrologic Process Study of Lake El

这个试点项目将开始研究西伯利亚与世隔绝的El‘gytgyn湖附近的气候和水文。这个独特的湖泊是大约360万年前由一颗流星撞击形成的。其他获得资助的项目正在通过检查西伯利亚湖中未受干扰的沉积物来评估东西伯利亚的气候历史。拟议的项目将在湖的一个溪流入口处放置一个完整的气象塔，以测量降雨量、气温、土壤湿度、太阳辐射、相对湿度、积雪深度和土壤温度。这些数据将开始对当地气候进行基线测量。将在2000年夏季的6周内收集数据，并在今后两年内将仪器留作自动收集。这些数据将被用来开始评估东西伯利亚的水文循环，这是一个我们目前对区域气候学了解薄弱的地区。这项工作可以为今后更广泛地研究西伯利亚的植被和水循环奠定基础，遵循目前在阿拉斯加冻土带进行的研究模式。

This pilot project will begin a study of the climate and hydrology near the isolated Lake El'gygytgyn in Siberia. This unique lake was formed by a meteor impact about 3.6 million years ago. Other funded projects are evaluating the climate history of eastern Siberia by examination of the undisturbed sediments in the Lake. The proposed project would place a full meteorological tower at one of the stream inlets to the Lake in order to measure precipitation, air temperature, soil moisture, solar radiation, relative humidity, snow depth, and soil temperature. This data will begin baseline measurements of the local climate. Data would be collected during 6 weeks in summer 2000 and instruments left for automated collection over the next 2 years. The data would be used to begin an evaluation the hydrological cycle in eastern Siberia, a region where our current understanding of regional climatological is weak. This work could form the basis for more extensive future research on the vegetation and water cycles of Siberia following the research format presently occurring in the Alaskan tundra.
