研究了基于轮廓的海量气象雷达反射率数据高度压缩方法，以优化压缩和重建参数。特别是，研究了编码和检索端的阈值选择和平滑程度对可实现的压缩比、检索轮廓的均方根误差以及重建反射率图像的视觉保真度的影响。给出了多个实际多普勒天气雷达反射率数据集的结果
Studies are carried out on a contour-based method for highly compressing voluminous weather radar reflectivity data to optimize the compression and reconstruction parameters. In particular, the effects of the choice of thresholds and the degree of smoothing at encoding and retrieval ends are studied with respect to achievable compression ratios, root-mean-square error of the retrieved contours, and the visual fidelity of the reconstructed reflectivity images. Results are presented for multiple actual Doppler weather radar reflectivity data sets
