Weather Radar Observation

Weather radar is a remote sensing instrument which is used to locate precipitation, measure its intensity, and calculate its motion by sending out microwaves that can be reflected back to the radar by precipitation particles in the air. As it can three-dimensionally detect precipitation events such as heavy rain, typhoon, and hail for a short period of time, the radar is used for early detection and forecasting of severe weather events.

The Korea Meteorological Administration (KMA) operates 11 radars across the country―in Baeknyeongdo, Gwanaksan in Seoul, Gwangdeoksan in Hwacheon, Gangneung, Oseongsan in Gunsan, Jindo, Myeonbongsan in Cheongsong, Gudeoksan in Busan, Gosan and Seongsan in Jeju, and Incheon International Airport in Youngjongdo. Observation data from weather radars undergo quality control and then they are processed into images to be distributed to the public on websites and mobile apps.

In 2010 the KMA concluded a MoU with the Ministry of Land, Infrastructure, and Transport and the Ministry of National Defense for joint use of weather radar data. Under the MoU, they implemented a data-sharing system in 2012, and since then they started sharing the data with one another. The KMA also exchanges weather radar data with its neighboring countries such as China, Japan, and Russia to use them for monitoring and predicting weather conditions in East Asia.
