衰减校正方法的最新进展是基于使用由路径中每个距离单元共享的沿着路径遇到的衰减总量表示的约束，该技术通过使用雷达测量的内部自一致性来改进。完全自洽方法提供了一种优化程序，用于获得特定和累积衰减以及特定和累积差分衰减的最佳估计。这项研究的主要目标是检查液滴尺寸分布（DSD）检索X波段雷达测量衰减校正后。一种新的技术，估计线性轴比模型的斜率从极化雷达测量衰减频率的设想。一组新的改进算法免疫的雨滴形状-尺寸关系的变化，提出了用于估计的γ雨滴尺寸分布的控制参数。基于T…
Abstract The recent advances in attenuation correction methodology are based on the use of a constraint represented by the total amount of the attenuation encountered along the path shared over each range bin in the path. This technique is improved by using the inner self-consistency of radar measurements. The full self-consistency methodology provides an optimization procedure for obtaining the best estimate of specific and cumulative attenuation and specific and cumulative differential attenuation. The main goal of the study is to examine drop size distribution (DSD) retrieval from X-band radar measurements after attenuation correction. A new technique for estimating the slope of a linear axis ratio model from polarimetric radar measurements at attenuated frequencies is envisioned. A new set of improved algorithms immune to variability in the raindrop shape–size relation are presented for the estimation of the governing parameters characterizing a gamma raindrop size distribution. Simulations based on t...
