As part of the long-established close working relationship between WMO and ICAO, e.g. World Area Forecast Centre (WAFC), Tropical Cyclone Advisory Centre (TCAC), and Volcanic Ash Advisory Centre (VAAC). These centres provide specialized warning services for the aviation community.
The ICAO Meteorology Panel (METP) noted an update to a concept of operations for space weather that would enable an operational global space weather information service for aviation in the 2018 timeframe, and guidance on the space weather information provider designation process.
One of the key components in the realization of an operational, global space weather information service for aviation before the end of 2018 is the conducting, by WMO at ICAO’s request, of site assessments and audits of prospective space weather information providers.

ICAO in cooperation with WMO established a framework for the International Airways Volcano Watch (IAVW) in 1993. Within this framework, nine Volcanic Ash Advisory Centers (VAACs) monitor volcanic eruptions and provide information on the locations and movement of volcanic ash in their areas of responsibility, as soon as volcanic ash is reported or detected (volcano observatory, pilot report, satellite imagery, etc.)
