This dataset contains hydrological data from the Khujand Hydrological Station located 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 of the National Academy of Sciences of Tajikistan, and the Tajik Hydrometeorological Service. This dataset is applicable to scientific research such as water resource assessment in the mountainous areas of Central Asia, as well as services for 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 (mm)

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