The various regional conflicts escalating in Southeast Asia during the years 1961 through 1975 were causal for reactivating the 10th Weather Squadron on 8 July 1966 at Udorn Royal Thai Air Force Base in Thailand, to conduct combat weather operations in Southeast Asia. The 10th subsequently relocated to Long Binh AI, RVN, 3 Aug 1967 and then to Nakhon Phanom, Thailand, 18 February 1974 before being inactivated 30 June 1972. The squadron trained indigenous weather personnel and set up the clandestine weather observation networks throughout Southeast Asia. The 10th Weather Squadron played an important part in the raid on the Son Tay POW camp (a.k.a. Operation Ivory Coast) of 1970. The weather forecasting for this mission primarily relied upon images obtained from Defense Meteorological Satellite Program (DMSP) satellites, data obtained by weather aircraft reconnaissance sorties, and extensive climatic analysis data. Weather forecaster Major Keith R. Grimes who as Lt Col became the commander of the 10th during the period from 7 July 1974 to 15 Jul 1975 was weather advisor to the Joint Task Force Commander planning Operation Ivory Coast. It is Major Grimes' extensive work with climatological data and forecasts prepared by Air Weather Service personnel credited by Air Weather Service historians as setting raid's general date.
