中亚锡尔河流域水文资料（2020）

本数据为锡尔河中游苦盏水文站水文资料。该站为中国气象局乌鲁木齐沙漠气象研究所和塔吉克斯坦国家科学院水问题水能与生态研究所、塔吉克斯坦水文气象局合作建设。该数据可以用于中亚山区水资源评估等科学研究和水利工程等服务。
资料时段：2019年11月2日至2020年12月5日。
资料要素：逐小时流速（m/s）、逐小时水位（m）和逐小时降雨量（m）
站点位置：40°17′38″N, 69°40′18″E，320m
一、300W-QX河流流速、水位观测仪
（一）流速参数：
1供电电压 12（9~27）V(DC)
2工作电流 120（110~135）mA
3工作温度（-40 ~85） °C
4测量范围 （0.15 ~20）m/s
5测量精度 ±0.02m/s
6分辨率 　 1mm
7探测距离 0.1~50 m
8安装高度0.15~ 25 m
9采样频率 　 20sps
（二）水位参数：
1测量范围 0.5~20 m
2测量精度 ±3 mm
3分辨率 　 1 mm
4重复性 　 ±1mm
二、SL3-1翻斗式雨量传感器
1承水口径 ф200mm
2测量降水强度 4mm/min以内
3测量最小分度 0.1mm降水量
4最大允许误差 ±4%mm
三、流速、观测仪数据获取的频率：传感器每隔5S测量一次流速和水位数据
四、小时平均流速计算：小时平均流速和水位数据由一小时内所有每隔5S测量的流速和水位数据取平均计算得出
五、水位数据中大量出现的0值的说明：水位数据中0值是供电不足引起传感器断电重启，重启后第一条数据为0，导致小时平均值出现0。2019年12月5日供电改造后恢复正常
六、雨量数据中有部分缺失及-8.191mm等非正常数据，应该予以剔除和说明。
数据缺失4.10-5.3数据，已补充，-8.191mm类似这种异常数据已经标记

This dataset contains hydrological data from the Khujand Hydrological Station in the middle reaches of the Syr Darya River. This station was jointly constructed by the Institute of Desert Meteorology, China Meteorological Administration (Urumqi), the Institute of Water Problems, Hydropower and Ecology, Academy of Sciences of Tajikistan, and the Tajik Hydrometeorological Service. This dataset can be used for scientific research such as water resource assessment in Central Asian mountainous areas, as well as services for water conservancy projects.

Data Period: November 2, 2019 to December 5, 2020.
Data Elements: Hourly flow velocity (m/s), hourly water level (m), and hourly rainfall (mm)

Station Location: 40°17′38″N, 69°40′18″E, elevation 320 m.

1. 300W-QX River Flow Velocity and Water Level Observation Instrument
(1) Flow Velocity Parameters:
1. Power Supply Voltage: 12 (9~27) V (DC)
2. Operating Current: 120 (110~135) mA
3. Operating Temperature: (-40 ~ 85) °C
4. Measurement Range: (0.15 ~ 20) m/s
5. Measurement Accuracy: ±0.02 m/s
6. Resolution: 1 mm
7. Detection Distance: 0.1~50 m
8. Installation Height: 0.15 ~ 25 m
9. Sampling Frequency: 20 sps

(2) Water Level Parameters:
1. Measurement Range: 0.5 ~ 20 m
2. Measurement Accuracy: ±3 mm
3. Resolution: 1 mm
4. Repeatability: ±1 mm

2. SL3-1 Tipping Bucket Rainfall Sensor
1. Water Receiving Caliber: φ200 mm
2. Measurable Precipitation Intensity: ≤4 mm/min
3. Minimum Measurement Graduation: 0.1 mm of precipitation
4. Maximum Allowable Error: ±4% mm

3. Data Acquisition Frequency of Flow Velocity and Water Level Observation Instrument: The sensor measures flow velocity and water level data every 5 seconds.

4. Hourly Average Flow Velocity Calculation: The hourly average flow velocity and water level data are calculated by averaging all flow velocity and water level data measured every 5 seconds within one hour.

5. Explanation of Zero Values in Water Level Data: The zero values in the water level data are caused by power supply insufficiency leading to sensor power outage and restart, with the first data after restart being 0, which results in zero hourly average values. Normal operation was restored after the power supply upgrade on December 5, 2019.

6. Note on Rainfall Data: Some rainfall data are missing, and there are abnormal data such as -8.191 mm, which should be excluded and explained.

The data from April 10 to May 3 was missing and has been supplemented. Abnormal data similar to -8.191 mm have been marked.
