RAPID: Snow Sensor Maintenance in Boulder Creek and Jemez River Basin CZOs

该项目将在Boulder Creek(BC)和Jemez River(JRB)盆地临界区天文台(CZO？S)维护分布式积雪传感器阵列。这些积雪传感器阵列是对现有CZO基础设施的补充。这些雪传感器阵列，与中国地质调查局S现有的仪器相结合，创建了水文仪器群，以探索水文和生态过程之间的反馈，约束水和碳通量的模型，并提高对气候变化相关生态影响的预测。这些雪传感器阵列与Krew(Sierra CZO)的传感器阵列兼容，代表了一个共同定位的雪、土壤和植被水分利用测量的全面网络。继续维护积雪测量将使数据采集能够在2010-11年冬季继续进行，没有数据缺口。该项目与塞拉利昂CZO合作，为跨这三个临界区观测站的分布式积雪水文测量网络设计奠定了基础。虽然拟议研究的重点是继续和维持已经启动的积雪测量计划，但收集的数据集和跨CZO的协作将为更统一和更广泛的跨CZO积雪测量网络奠定基础。这些数据对于建立地形变异性与积雪分布和融化模式之间的一般关系很重要。CZO计划首次允许对代表美国西部的三个不同山区制度的各种时间气候变化进行持续努力。

The project will maintain distributed snow sensor arrays in the Boulder Creek (BC) andJemez River (JRB) Basin Critical Zone Observatories (CZO?s). These snow sensor arrayscomplement existing CZO infrastructure. These snow sensor arrays, combined with existing instrumentation at the CZO?s, create hydrologic instrument clusters to explore feedbacks between hydrological and ecological processes, constrain models of water and carbon fluxes, and improve predictions of ecosystem impacts associated with climate change. These snow sensor arrays are compatible with those operating at KREW (Sierra CZO) and represent a comprehensive network of co-located snow, soil, and vegetation water use measurements. The continued maintenance of the snow measurements will enable data acquisition to continue in winter 2010-11 without data gaps.This project, in cooperation with the Sierra CZO, lays the foundation for a distributed snow hydrology measurement network design across these three Critical Zone Observatories. While the emphasis of the proposed research is on continuing and maintaining snow-measurement programs already initiated, the data sets collected and collaboration across CZOs will lay the foundation for a more-uniform and broader cross-CZO snow-measurement network. These data are important in establishing general relationships between physiographic variability and patterns of snow distribution and melt. The CZO program allows for the first time a sustained effort over various temporal climatic variations in three different mountain regimes that are representative of the Western U.S.
