Disdrometer and condensation nuclei (CN) data are compared with operational polarimetric radar data for one multicell and one supercell storm in eastern Nebraska on 11 June 2018. The radar was located ~14.3 km from the instrumentation location and provided excellent observation time series with new low-level samples every 1–2 min. Reflectivity derived by the disdrometer and radar compared well, especially in regions with high number concentration of drops and reflectivity < 45 dBZ. Differential reflectivity also compared well between the datasets, though it was most similar in the supercell storm. Rain rate calculated by the disdrometer closely matched values estimated by the radar when reflectivity and differential reflectivity were used to produce the estimate. Concentration of CN generally followed precipitation intensity for the leading convective cell, with evidence for higher particle concentration on the edges of the convective cell associated with outflow. The distribution of CN in the supercell was more complex and generally did not follow precipitation intensity.

内布拉斯加州东部2018年6月11日超级电池和多电池风暴的测速仪，极化雷达和凝结核观测

于2018年6月11日，比较了内布拉斯加州东部一处多小区和一处超级小区风暴的测速仪和凝结核（CN）数据与操作极化雷达数据的对比。该雷达距离仪器位置约14.3 km，提供了极佳的观测时间序列，且具有新的低点每1-2分钟进行一次水平采样。用测距仪和雷达得出的反射率比较好，尤其是在液滴浓度较高且反射率<45 dBZ的区域。差异反射率在数据集之间也进行了很好的比较，尽管在超级单元风暴中最相似。当使用反射率和微分反射率进行估算时，由测速仪计算出的降雨率与雷达估算出的值非常匹配。前导对流池中CN的浓度通常跟随沉淀强度，证据表明与流出相关的对流池边缘上的颗粒浓度较高。CN在超级电池中的分布更为复杂，通常不遵循降水强度。
