Hydrological observation data of Central Asia's SYR River Basin (2021)- A Big Earth Data Platform for Three Poles

This data is the hydrological data of the Khujand Hydrological Station in the middle reaches of the Syr Darya. The station is jointly constructed by the Urumqi Desert Meteorological Institute of the China Meteorological Administration, the Institute of Water Issues, Hydropower and Ecology of the National Academy of Sciences of Tajikistan, and the Tajikistan Hydrological and Meteorological Bureau. This data can be used for scientific research such as water resource assessment in Central Asia and services such as water conservancy projects.

Data period: December 5, 2020 to September 11, 2021.

Data elements: hourly flow velocity (m/s), hourly water level (m) and hourly rainfall (m)

Site location: 40°17′38″N, 69°40′18″E, 320m

3. Frequency of flow rate and observation instrument data acquisition: The sensor measures the flow rate and water level data every 5S

4. Hourly average flow rate calculation: The hourly average flow rate and water level data are calculated from the average of all flow rate and water level data measured every 5S within one hour

File naming and required software

Data file naming and usage
File naming: The data is stored in the table xls format, and the file name is "Hydrological data from Syr River in Tajikstan (2021)", which can be opened and read by office software such as Office and Wps.
From left to right, each column of data is:
Average velocity (m/s)
Maximum flow velocity (m/s)
Minimum flow velocity (m/s)
Average water level (m)
Maximum water level (m)
Minimum water level (m)
Rainfall (mm)
