Abstract :
Sampling errors of space-time average rain rate in 1-30 day integration times and 0.1°-5.0° space domains, for simulated GPM (Global Precipitation Measurement) eight-satellite group, were estimated using 3-year radar-AMeDAS composites data around Japan. Moreover, we formulated sampling error RMS (%) as a function of space scale A (degree), time scale T (day), and true average rain rate R (mm/h).
