Abstract

This study reviews combined rainfall observation using both radar and rain gauges. Sampling error theory is introduced and applied to an evaluation of the rain gauge network of the upstream region of the Imjin River Basin in North Korea. Under the assumption that the Ganghwa Radar is properly calibrated, an additional 13 rain gauges (including the eight that are currently in operation) is deemed sufficient to secure the quality of rainfall observation with 37 rain gauges without radar.
