[ACG34-P10] Comparison between high frequency satellite rainfall estimation and APHRODITE-2 ground rain gauge observation
Keywords:Precipitaition, Satellite, APHRODITE
Since the above satellite rainfall observation data can estimate global precipitation every hour, it is possible to create daily average data in which the average section is shifted by one hour. By correlating the satellite daily precipitation observation time series with the APHRODITE daily precipitation observation time series, the EOD value in each country was estimated from the time when the correlation coefficient is largest. We confirmed that the reliability of this method is high by a verification analysis in the field where true value of EOD is already known. Moreover, we made pseudo hourly rain time series of APHRODITE by inserting APHDOITE daily rain time series to satellite hourly rain time series. By this method, we will try to make a new APHRODITE data that is corrected for the EOD difference between each country.
