• 5.5 trillion won of property loss due to Typhoon RUSA (September 2002)
• Flood damage due to heavy rains (260mm/day) in Gwanghwamun, Seoul (September 21, 2010)

• Weather radar is the most effective detection equipment for detecting, tracing, and monitoring the severe weather phenomena such as heavy rain and typhoons by using signals in which weather radar sends electromagnetic waves continuously at several heights with a 360-degree rotation, and its waves are reflected by rain, snow, and hail.

• Maximized sharing and joint-use of the radar at each department and its technologies to detect severe weather and improve forecasting capabilities.
• America operates Radar Operation Center (ROC) with three of the departments (National Weather Service, Ministry of National Defense, and the Federal Aviation Administration) in conjunction. (168 same models of radar and cost sharing through the joint-use of radar)
• The EU co-operates 193 radar systems with 29 countries. (France, Greece, etc.)

• Changed the combined radar operation system with the separately-operated radar systems for the efficiency of radar operation and technical development. Established the Weather Radar Center with surplus manpower (Apr. 2010).
• Scheduled to replace the existing setup with the dual-polarimetric radar (S-band) of good performance for radar standardization and ease of reducing operational costs (2011~2016)

• Established and operated the Radar Policy Council with the director or manager for each department, and the working-level meeting and the Advisory Committee for supporting the Radar Policy Council (Jul. 2010)
• Study for advanced examples of radar joint-use (America Radar Operation Center) (November~December 2010)
• Established a basic plan for joint-use of data with radar systems (Nov. 2010), detailed promotion plan (Apr. 2011), and a strategy plan for information (May. 2011)

Radar operation costs have been growing as various models of radar and software have been operated (two wavelengths, five manufacturers, four productions), but its quality control, precipitation forecasting, and technology are insfficient.

• Secured the spare parts for each wavelength and manufactured parts in order to prepare for malfunctions; training for maintenan ce is necessary.
• Absence of technology exchange and space for cooperation to perform the effective Radar Administrative Convergence

• Solved 53% of observation blind spots, on average (18 points at KMA, 61 points at the Ministry of Land, Infrastructure and Transport, and 80 points at the Ministry of National Defense)

•

• Pan-government increased radar systems’ effect and budget reduction effect: the amount of 162 billion won
• Additional budget reduction possibilities through sharing spare parts and the co-development and co-operation of technology

• Complementary operation with other departments’ radar in surrounding areas when missing radar observation Improved monitoring of heavy snowfall in winter and forecasting efficiency (use the Mt. Biseul radar)
• Agreement to build up the radar test bed for cooperation for radar technology development (April. 2011)
• Set to localized weather radar development using R&D of the Ministry of Knowledge Economy (2011~2015, amount of 78 million won)
