Monthly average rain rate over latitude-longitude grids of 5°× 5° is estimated from instantaneous rain rate data obtained by Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar(PR). There are two methods to estimate monthly average rain rate from TRMM PR data. One is the sample average of instantaneous high-resolution rain rate data which is corrected for rain attenuation. The other is the statistical average estimated from probability distribution function by using multiple threshold method. In this paper, through the comparison between sample average and statistical average, it is shown that the statistical method can estimate rain rate reasonably well if appropriate threshold values of rain rate and rain attenuation are selected. |
