Abstract :
Sampling error of rainfall rate was estimated by using radar-AMeDAS composites in 5°×5° and 1°×1° grid box for five sun synchronous orbit satellites and TRMM. It was influenced by satellite altitude, swath width, local time. Sampling error caused by altitude ocuppied half of sampling error. It was discovered that sampling error depend on sampling period as period- 12 /.
