Real Weather Radar Data Doppler Processing to retrieve Radial Wind and Raindrop Size Distribution (DSD) Parameters

This repository contains the data acquired from the MESEWI weather radar at the Delft University of Technology for Doppler processing. It contains MATLAB code for estimating the raindrop size distribution (DSD) parameters (sub-optimal estimates) and the radial mean wind and turbulence parameters. In addition to the DSD estimates, this code can generate the Plan Position Indicator (PPI) plots for terminal fall velocity and median diameter as a function of range and azimuth. This novel estimator can make use of these incoherent radar fast scans to estimate the parameters.<br>The MESEWI radar is an X-band azimuthally scanning radar at TU Delft, Netherlands. The data folder contains the data for several azimuthal radar scans at an elevation of 30 degrees from the ground level. The code files are in the folder Production4TURD. Details of the code repository can be found in the README.pdf file.

本代码仓库包含荷兰代尔夫特理工大学（Delft University of Technology）MESEWI气象雷达（MESEWI Weather Radar）采集的、用于多普勒处理的观测数据。仓库内附带用于估算雨滴尺寸分布（raindrop size distribution, DSD）参数（次优估计结果）、径向平均风及湍流参数的MATLAB代码。除雨滴尺寸分布参数估计外，该代码还可生成终端下落速度与中值直径随距离和方位角变化的平面位置显示器（Plan Position Indicator, PPI）图。这款新型估计算法可借助此类非相干雷达快速扫描数据完成参数估计。
MESEWI气象雷达是部署于荷兰代尔夫特理工大学的X波段方位扫描雷达。数据文件夹包含多组仰角为30度（距地面）的方位扫描雷达观测数据，代码文件存放于Production4TURD文件夹中。本代码仓库的详细说明可参阅README.pdf文件。
