This report describes a procedure to complete missing data of hourly sunshine duration in AMeDAS data. Mainly two completion methods have been examined. The first one is to replace the missing hourly sunshine duration by the data observed at one of the surrounding AMeDAS stations. On applying this method, the procedure to select the most appropriate surrounding station is necessary. The second one is to generate the missing data by linear interpolation using the data observed at the same station. Since the accuracy of the second method decreases in proportion with the length of the missing period, it can only be applied when the missing period continues less than the threshold hours investigated in advance in order to be applicable to various cases. Missing hourly sunshine duration in AMeDAS data during 1981 through 1995 have been completed by combining the two methods described above.
