Yuma rain and stream stage

This dataset includes tipping bucket rain gauge and ephemeral stream stage data from Mohave and Yuma Wash

Locations of each measurement are included in locations.txt

Background: Details about the monitoring sites are available in Faulconer (2015). Thresholds for runoff generation in ephemeral streams with varying morphology in the Sonoran Desert in Arizona, USA. MS Thesis, Colorado State University https://mountainscholar.org/handle/10217/166929

Sensors: Rain gauges were TE525 and TB4 tipping buckets attached to Campbell Scientific loggers and RG3-M tipping buckets with Onset HOBO pendant event loggers
Stage sensors were In-Situ Inc. Rugged Troll 100 unvented pressure transducers.

Stage data included here were adjusted for barometric pressure and partially offset adjusted to bring no flow stage closer to zero at the beginning of the time series. Most values in each time series are
sensor noise, which is +/- 2 cm. Stream flow is only when stage rises >2cm above background stage. Background stage values can drift, so absolute stage should not be compared between sites or between events.

Note, sensors may have periods of missing data due to sensor failures.

本数据集涵盖采自莫哈韦（Mohave）与尤马干谷（Yuma Wash）的翻斗式雨量计（tipping bucket rain gauge）及间歇河流（ephemeral stream）水位监测数据。
各监测点位的坐标信息详见locations.txt文件。

背景信息：监测站点的详细说明可参阅Faulconer(2015)发表的硕士学位论文《美国亚利桑那州索诺兰沙漠不同地貌间歇河流的产流阈值》，该论文为科罗拉多州立大学硕士学位论文，可通过https://mountainscholar.org/handle/10217/166929获取。

传感器配置：雨量计采用TE525、TB4型翻斗式雨量计（配套Campbell Scientific数据采集器）以及RG3-M型翻斗式雨量计（搭配Onset HOBO Pendant事件记录器）；水位传感器采用In-Situ Inc.的Rugged Troll 100型非通气式压力传感器。

本次提供的水位数据已进行气压校正，并完成部分偏移量调整，以使时间序列初始时段的无流水位趋近于零。各时间序列中的绝大多数数值为传感器噪声，其波动范围为±2 cm。仅当水位较背景水位升高超过2 cm时，方可认定存在径流。背景水位可能发生漂移，因此不得在不同监测站点或不同事件之间直接对比绝对水位值。

请注意：因传感器故障，部分监测时段可能存在数据缺失情况。
