Verification of the effect of quality control implementation to increase accuracy of rainfall estimation in Lombok areas

C-Band Doppler Weather Radar is one of the supporting instruments used in the meteorology for weather forecasting and analysis in Lombok region. One of the purpose of weather radar is estimates the rainfall rates in a wide range and long period, but in the process radar possess limitation called "radar limitation" causes data generated by the radar is inaccurate, this can be overcome by implementing quality control. The purpose of this study is to improve the estimation of rainfall using radar products with the step of Clutter Correction (PPI), Bright Band Echoes (MAX) and Z-attenuation (SRI) to be compared SRI products then convert to RIH and PAC that show the value of rainfall rates estimation with data from AWS/ARG in the Lombok area then verified with RMSE values and correlation values to represent the estimated amount of rainfall that can support operations using weather radar. The results of the research obtained published that quality control is very necessary in improving the quality of the results and the quality of the rain reported in the Lombok. Comparison of the results after quality control and non-quality control showed better results after quality control was performed.
