Kajian Impelementasi Quality Control Faktor Bright Band dan Atenuasi Radar Cuaca C-Band

Abstrak

Weather radars have several limitations there are bright band echoes and attenuation of electromagnetic wave from radars beam. The purpose of this research is to conduct an analysis respect to the result of quality control from both of the limitations in 2019 which divide into four case study. Freezing level height of radiosonde used for support the identification activity of BBC phenomena. The result of BBC can reduce the BBE patterns however, it unable to function optimally in reducing all parts of the BBE patterns. Rainfall attenuation correction that have been done shows various results, either quantitatively or qualitatively. Attenuation correction is able to increase the rainfall value in product image SRI and PAC qualitatively. Quantitative analysis shows that the r and MAE values after attenuation correction of hourly rainfall have a good value besides that the attenuation correction in daily rainfall data is able to improve the estimate by 62.5%.
