Stage-discharge rating curves (DP4.00133.001)

This data product provides parameters that describe the relationship between manual staff gauge readings and manual and/or instumental discharge measurements for NEON stream, river, and lake inflow and outflow locations. The parameters provided are the coefficients defining an exponential curve and are derived from manually measured discharge (manually or via ADCP) and staff gauge readings by a Bayesian model. Rating curve parameters published in this product are used together with sensor measurements of surface water pressure to calculate the Continuous discharge (DP4.00130.001) data product. Data users should refer to the user guide for Stage-discharge rating curve (NEON\_ratingCurve\_userGuide) for more detailed information on the algorithm used to develop a rating curve. Latency: Data are generated once per year and are expected to be available each December following the end of the water year (October 1 - September 30).

本数据产品提供用于描述NEON所辖溪流、河流及湖泊入流与出流点位的人工水位尺（staff gauge）读数与人工和/或仪器流量测量值之间关系的参数。本次提供的参数为定义指数曲线的系数，由人工实测流量（通过人工方式或ADCP（Acoustic Doppler Current Profiler）获取）与水位尺读数通过贝叶斯模型（Bayesian model）推导得到。本产品发布的水位流量关系曲线（rating curve）参数，需与地表水压力传感器测量值结合使用，以计算连续流量（DP4.00130.001）数据产品。数据使用者可参阅《水位-流量关系曲线用户指南（NEON_ratingCurve_userGuide）》，以获取关于水位流量关系曲线构建算法的详细信息。数据发布时效：本数据按年度生成，预计于水文年度（10月1日至次年9月30日）结束后的12月对外发布。
