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

Pilots on international routes, such as 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.

This is the North tower site at Reigate hill,Not the Arqiva site south as mentioned by every database on the internet. The site visit and confirmed frequency of volmet main is 135.382,560, AM carrier 50W erp calculated from 212m from the base of the mast with -30dB attenuation inline,then measured at 15 miles no attenuation signal 9 +10dB The closest channel based on the 8.33KHz spacing is 135.383,330 MHz as from the rollout in 1999.
