Abstract
This work proposed a method by which disaster prevention weather information standards based on rain gauges can be constructed. First, we compared the difference between rain gauge and radar rain gauge analyzed precipitation, and confirmed that there was a significant difference between them. These results showed that disaster prevention weather information using rain gauges requires modification based on the radar rain gauge analyzed precipitation. Second, we proposed a method to set a rain gauge correction standard based on the disaster prevention weather information. The proposed correction standard agreed almost fully with the number of times that the disaster prevention weather information standard was exceeded. Third, we installed a new rain gauge and obtained a disaster prevention weather information standard using the proposed method described. Through reproduction analysis, we obtained the same results as the disaster prevention weather information that was used and were able to detect disaster cases during the data collection period of the newly installed rain gauge.
