The country’s first modern meteorological observation was carried out at the Incheon Meteorological Observatory founded by Imperial Japan right before the Russo-Japanese War (1904-1905). However, Imperial Korea (1897-1910) also started making meteorological observations on its own around that time. Meteorological observatories were also erected in Pyongyang and Daegu in 1907.
In 1949, the Central Meteorological Office (CMO) was established. In 1990, the CMO was upgraded to the Korean Meteorological Administration (KMA).
The Seoul Meteorological Observatory building was first built eighty years ago as the Gyeonggi-do Municipal Gyeongseong Rain Gauge Station and has been used as a meteorological observation station ever since. The building is an early-modern hexagonal structure with a round column at the center.
