WMO-CIMO Lead Centre on Evaluation of Precipitation Measurement Accuracy - Chupungnyeong (Republic of Korea)

"The regulation for the management of the standard meteorological observatories" was enacted and this site was designated as Korean Standard Weather Observatory for sensor performance testing and intercomparison observation by Korea Meteorological Administration (KMA) in 2008. Afterwards, Chupungnyeong is the core observatory for the KMA’s standardization project. Additionally, another standard meteorological observatory was established in 2010 under the MOU between KMA and the local government of Gochang-gun. Chupungnyeong and Gochang sites are closely linked to the KMA’s Standardization Project. Gochang is located at the west coast of Korea, which is characterized with several heavy snow events, caused by the cold surge over the Yellow Sea, and is to be considered as a part of Chupungnyeong as the WMO CIMO Lead Centre.

Since 2009, KMA has been in charge of the WIGOS Demonstration Project in WMO RA II region of “Establishment of a Common Information Infrastructure for Meteorological Observation Data” which aims at the integration and co-use of meteorological observation data produced by diverse domestic agencies. There were several intercomparison experiments, such as:

• Investigation of the wind screen effect for the rain gauges, 
• Experimental operation of weighing precipitation gauge: Double Fence Intercomparison Reference (DFIR) and Pit Gauge,
• Collaboration international activity: WMO Solid Precipitation Intercomparison Experiment (SPICE).
