On September 25-26, 2025, the 36th session of the Interstate Council on Hydrometeorology of the Commonwealth of Independent States was held in Tashkent (Republic of Uzbekistan).

The event brought together representatives from nine CIS countries, the World Meteorological Organization (WMO), CIS Executive Committee, and Interstate Aviation Committee (IAC) to discuss current issues.

The national hydrometeorological services of the CIS countries reported on their activities and cooperation within the CIS and WMO. They also reported on the operation of the ground-based observation network and the results of monitoring the activities of the CIS interstate hydrometeorological network in 2024-2025.

In particular, the following issues were reviewed:
