Kyu Rang Kim


Korea Meteorological Administration, Republic of Korea

Dr. Kim is leading the Biometeorology Research team of the National Institute of Meteorological Services (NIMS) of the Korea Meteorological Administration (KMA) since 2006. His research interest is in heat and cold stress assessment of human, pollen allergy forecast, and agro-meteorology. He is also a member of the Standing Committee on Services for Agriculture. He developed a nation-wide Heat Health Warning System based on Perceived Temperature (PT) and local ensemble forecast to implement an impact-based forecast for heat waves in Korea. PT was first introduced from Germany (DWD) and investigated to represent heat/cold stress of Koreans using climate chamber experiments. PT was far better explaining heat-related mortality and morbidity than ordinary air temperature in Korean cities. He suggests observation of black globe temperature (GT) at standard meteorological stations. Observed GT can be used to calculate radiant temperature, which holds the key component assessing human heat stress. Various types of downscaling methods as well as high resolution (~10 m) GIS data were incorporated to estimate weather conditions including air and radiant temperatures and wind speed at pedestrian height in urban and agricultural areas. Pollen monitoring network in Korea is composed of 12 Burkard samplers and is operational since 1997. He developed forecast models based on deep neural network and statistical models for pollen allergy to be publicly serviced by KMA. Automation of the observational network is his current vision for better accuracy and sustainability of pollen allergy services.
