A Watershed-Scale Hydrologic Process Study of Lake El

该试点项目将开始对西伯利亚孤立的El'gygytgyn湖附近的气候和水文进行研究。 这个独特的湖泊是由大约360万年前的流星撞击形成的。其他受资助的项目正在通过检查湖中未受干扰的沉积物来评估东西伯利亚的气候历史。 拟议的项目将在湖泊的一个溪流入口处放置一个完整的气象塔，以测量降水、气温、土壤湿度、太阳辐射、相对湿度、雪深和土壤温度。 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个星期内收集数据，仪器将在今后2年内自动收集。 这些数据将用于开始评估东西伯利亚的水文循环，我们目前对该地区气候的了解还很薄弱。 这项工作可以形成的基础上，更广泛的未来研究的植被和水循环的西伯利亚的研究格式目前发生在阿拉斯加苔原。

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.
