要約(英語): In this paper, we present the results of the validation of solar radiation estimation using sunshine duration information of the Automated Meteorological Data Acquisition System (AMeDAS) Data provided by the Japan Meteorological Agency. The validation was carried out using insolation data of 20 points in the Hokuriku region. Because of the difference of the position between AMeDAS sites and insolation measurement points, the weighting that is inversely proportional to the distance was applied. Accuracy was evaluated by correlation coefficients and root mean square error. The correlation coefficient was 0.84-0.96, if a single point insolation was estimated. And the accuracy of about 0.98 was obtained when the average of 20 points in the Hokuriku region was estimated. Global solar radiation calculation method using AMeDAS is considered to have sufficient practical accuracy.
