易贡藏布下游逐时水深和水文观测数据（2020）

易贡藏布下游水文观测数据主要内容包括易贡藏布下游水深及水温小时监测数据，数据采集时间为2020年。数据来源为安装在易贡湖下游基岩上的HOBO水位计采集得到，HOBO水位计为压力传感式水位计，每小时采集存储一次，水深及水温数据均为每小时均值，其中需特别注意测量获得的水深数据为压力数据，转换为水深数据时应扣减测点当地大气压。该数据质量可靠、精度较高，可用于记录易贡藏布水位年内变化，并通过控制关键河道最终达到反演径流过程的目的。

The hydrological observation dataset of the lower Yigong Zangbo River primarily contains hourly monitoring data of water depth and water temperature in its lower reaches, with data collection completed in 2020. The data was acquired using a HOBO pressure-sensing water level gauge installed on the bedrock downstream of Yigong Lake. This HOBO gauge collects and stores data once per hour, and both the water depth and water temperature datasets are hourly averages. It is crucial to note that the initially measured water depth data is actually pressure-derived data; therefore, the local atmospheric pressure at the measurement site must be deducted during the conversion to actual water depth values. This dataset features reliable quality and high accuracy, and can be used to record the annual water level variations of the Yigong Zangbo River, ultimately achieving the goal of inverting the runoff process by focusing on key river channels.
