The Pioneer Venus Orbiter radio occultation experiment acquired vertical profiles of electron density in the ionosphere of Venus. These profiles were not readily accessible to researchers. Here we report the recovery and validation of a set of electron density profiles from Pioneer Venus Orbiter. More than 200 profiles spanning solar zenith angles of 30–170 were deemed acceptable for scientific analysis. These profiles sample solar minimum, moderate, and maximum conditions. The profiles are publicly available and ready for use in scientific investigations of the ionosphere of Venus and related topics.

从先锋金星轨道器无线电掩星观测中恢复和验证金星电离层电子密度剖面

Pioneer Venus Orbiter 无线电掩星实验获得了金星电离层电子密度的垂直剖面。研究人员不容易获得这些资料。在这里，我们报告了先锋金星轨道飞行器的一组电子密度剖面的恢复和验证。超过 200 个跨越 30-170 度太阳天顶角的剖面被认为可以进行科学分析。这些配置文件对太阳活动的最小值、中等和最大值条件进行采样。这些配置文件是公开可用的，可用于金星电离层和相关主题的科学调查。
