United Kingdom Warning and Monitoring Organisation

The United Kingdom Warning and Monitoring Organisation (UKWMO) was a British civilian organisation operating to provide UK military and civilian authorities with data on nuclear explosions and forecasts of fallout across the country in the event of nuclear war. The UKWMO was established in 1957 and funded by the Home Office and used its own premises which were mainly staffed by Royal Observer Corps (ROC) uniformed full-time and volunteer personnel as the fieldforce.
