International Aviation

The Met Office is one of only two World Area Forecast Centres (WAFC), known as WAFC London. Since 1984, it has provided global forecasts of upper winds, temperatures, and significant weather data (SIGWX) charts to optimise flight safety and fuel consumption, meeting Annex 3 to the ICAO Convention on Civil Aviation.

As one of nine Volcanic Ash Advisory Centres (VAAC), we cover eruptions in Iceland and the northeastern Atlantic, producing volcanic ash advisories.

We also deliver the Secure Aviation Data Information System (SADIS), supplying WAFS gridded and SIGWX data and Operational Meteorology (OPMET) data to aviation users in Europe, Africa, and parts of Asia.

Additionally, we collaborate on three Single European Sky ATM Research (SESAR) projects to provide aviation stakeholders with new tools and services for informed decision-making based on forecasts and observations.
