The Caspian Sea littoral states including Azerbaijan, Iran, Kazakhstan, Russia and Turkmenistan attend in CASPCOM meetings. The parties discuss and examine issues relating to the Caspian Sea such as the Water level fluctuations (WLFs) and climatic conditions. Moreover, they exchange information and data on the state of Caspian coast to prepare a catalog of meteorology and cooperation with the Tehran Convention for sustainable development of the Caspian Sea. 

At the opening of the meeting, Sahar Tajbakhsh, the deputy minister and head of Iran Meteorological Organization (IRIMO), referring to the importance of the Caspian Sea ecosystem as the largest landlocked lake in the world for the five neighboring countries, said: "Recently, due to climate change, the Caspian Sea has experienced water level fluctuations."

He continued: "Since the future of the Caspian Sea ecosystem is important for all of us, this meeting has been held so that the members of this working group can present their decisions and suggestions for the benefit of the whole region."

Tajbakhsh added: "For this purpose, the 25th Capscom meeting has been held and also from October 27 to 28, the scientific conference on climate change in the Caspian Sea will be held to pay more attention to this important region."

CASPCOM was established in 1994 by national hydrometeorological agencies (NMHSs) of the Caspian littoral states (Azerbaijan, Iran, Kazakhstan, Russia and Turkmenistan) with the support of the World Meteorological Organization (WMO).
