**VOLMET** (French origin *vol* (flight) and *météo* (weather report)), or **meteorological information for aircraft in flight**, is a worldwide [network](/source/Radio_network) of radio stations that broadcast [TAF](/source/Terminal_Aerodrome_Forecast), [SIGMET](/source/SIGMET) and [METAR](/source/METAR) reports on [shortwave](/source/Shortwave) frequencies, and in some countries on [VHF](/source/VHF) too. Reports are sent in [upper sideband](/source/Single-sideband_modulation) mode, using automated voice transmissions.

Pilots on international routes, such as [North Atlantic Tracks](/source/North_Atlantic_Tracks), use these transmissions to avoid storms and turbulence, and to determine which procedures to use for descent, approach, and landing.

The VOLMET network divides the world into specific regions, and individual VOLMET stations in each region broadcast weather reports for specific groups of air terminals in their region at specific times, coordinating their transmission schedules so as not to interfere with one another. Schedules are determined in intervals of five minutes, with one VOLMET station in each region broadcasting reports for a fixed list of cities in each interval. These schedules repeat every hour.

An aircraft in flight can obtain by VOLMET the Aviation routine weather reports (METAR) of specific airports.
