ESTIMATION OF PARAMETERIZATION FOR DROP SIZE DISTRIBUTION BASED ON MIE SCATTERING THEORY AND RADAR OBSERVATIONS IN SUMMER 2018

Abstract

 Radar observation is commonly used for rainfall observation and estimate the structure in clouds through wind speed. In this study, we observed rainfall and sea spray in the atmospheric boundary layer in the summer of 2018. A normalized radar cross section, which is an important parameter for radar observation, can be derived by assuming an arbitrary drop size distribution in the Mie scattering theory. Therefore, in this study, we propose an algorithm to estimate the parameters of the drop size distribution of rainfall and sea spray by comparing the normalized radar cross section obtained from observation with that obtained from the Mie scattering theory.
