Home > real time data Korea Enhanced Observing Period (KEOP) Damages from typhoon and severe weather in summer are more than 70 percent pf annual natural disaster. The sparce observational network opver the oceans frequently causes lower predictive accuracy of mesoscal severe weather phenomena in summer such as typhoon and heavy rainfall. The scientific objective of KEOP is to improve the prediction skill of severe weather (e.g. typhoon, heavy rainfall associated with the Changma front) in summer which is primarily based on the 3-Dimensional atmosphere and ocean intensive observations using the advanced instruments such as aerosonde and autosonde and mesoscale model-based application studies. In particular, the linkage with the international field experiments (CAMP, Argo) and the cooperation with Japan and China are essential for 3-dimensional and continuous observation and monitoring of typhoon, approaching toward Korean peninsula, over East China Sea. X-band Doppler Radar Study on accurate and appropriate radar data production focused on short term precipitation forecasting, rapidly developing storm system monitoring and precipitation mechanism study by X band doppler weather radar. Development of observation strategy for optimal use of operational weather radar and data managing strategy for studying on severe weather Array for Real-time Geostrophic Ocaenography (ARGO) Argo developments began in the year 2000. The Argo array is part of the Global Climate Observation System/Global Ocean observing system (GCOS /GOOS) and part of the Climate Variability and Predictability Experiment (CLIVAR) and the Global Ocean Data Assimilation Experiment(GODAE) Asian Pacific Regional Aerosol Characterization Experiment (ACE-Asia) ACE-Asia? - International cooperative program to understand how atmospheric aerosols influence the chemical and radiative properties of the Earth's atmosphere.
