Cover of sketch book of the 20th Weather Squadron in Korea

"This series of illustrations depicting the role played by the 20th Weather Squadron in the Korean conflict is dedicated to those who made the supreme sacrifice in the performance of their assigned tasks."

The 20th Weather Squadron came into Korea with the first Air Force contingent and served from Taejon back to the Pusan Perimeter and forward again to within sight of the Yalu River. It furnished weather service to all United Nations forces and operated from one end of Korea to the other, from air bases in the rear to enemy-facing forward positions.

"Immediately after the start of hostilities, 20th Weather Squadron forecasters joined the initial group of volunteer pilots sent to Korea. Mission: Afford close air support to United Nations Forces attempting to hold back the advancing North Korean hordes."

"Back in Japan, forecasters of the 20th brief tactical organizations for missions over Korea, then fly the mission with the organization in an effort to secure additional front line weather information."

"20th Weather Squadron Detachment 20-27, serving the Joint Operations Center, evacuates Taejon to set up operations at Taegu."

"Forecasters accompany B-29 tactical missions to secure and transmit weather observations from deep within enemy territory."

" 'Here comes 808.' 20th Weather Squadron C-47, 4315808, flying in equipment and supplies to weather men at an advanced base."

" '808' evacuating front line air base weather station while under enemy fire."

"Weather station at Korean east coast air base is the last unit to evacuate by sea and thwart communist trapping attempt."

"Radiosonde men of the 20th take a balloon run while under enemy sniper fire."

"Personnel of the 20th find that operating a tent type weather station subjects to flooded floors and a roof not too secure during a heavy wind."

"Moving again! Mobile weather station 'hits the road' toward its new location."

"Somewhere in Korea Staff Weather Officers of the 20th brief the Commanding General and Staff of the 8th Army, Commanding General and Staff of the 5th Air Force, Republic of Korea President Syngman Rhee and advisors, and U.S. Ambassador Muccio on weather for tomorrow's operations."

"20th Weather Squadron observers take observations at the front and radio the information to the rear areas."

"20th Weather Squadron observer Cpl. E.F. Vermillion, holder of the Bronze Star for gallantry, captures enemy soldier attempting attack on weather station."

"20th Weather Squadron forecasters examine a cache of Russian meteorological equipment uncovered in the captured communist weather station at Pyongyang."

"Back in Japan once again, personnel of the 20th trade their fatigues for refreshingly clean suntans and commence normal operations. Balancing the discomforts of combat operation against knowledge gained during their Korean sojourn, all agree the experience was very advantageous."
