Description

<p> Rain-gauge stations have been operated by many agencies, but temporal and spatial characteristics of the rain-gauge network have not been studied sufficiently. We studied the observation system and some characteristics of the rain-gauge network throughout Japan using available observed data of the Japan Meteorological Agency (JMA), the Water and Disaster Management Bureau under the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), and local governments (L-Gov).<br> Analysis results obtained using available observed data show different installed characteristics of rain-gauge networks among L-Gov observation systems. The JMA rain-gauge network decreased to 58 rain-gauge stations during 2008-2014. Most abandoned rain-gauge stations shared common features: rain-gauge stations were installed at high altitude, with high observation and maintenance costs. Regarding historical stored rainfall data of rain-gauge networks, approximately 90 % of JMA and MLIT rain-gauge stations have less than a 40-year historical store of data, with no missing rainfall data (hourly, daily, and annual).</p>
