摘要

作者研究了 2022 年 1 月 29 日至 30 日波罗的海南岸上空的纳迪亚飓风对永久性全球导航卫星系统台站相位测量的影响。为此,以 PPP 模式处理了位于波兰和俄罗斯联邦加里宁格勒州的 10 个对象的数据。从中减去了多径误差、星历误差和导航卫星时钟校正误差。研究发现,净化残差的标准偏差是飓风导致湍流活动增加的一个微弱指标。不过,简单地计算每日大的清洁残差总数,并将其与天顶方向归一化,可以作为识别对流层湍流高发期的有效指标。它既可用于遥感快速发展的天气过程,也可用于解释特别危险和技术复杂的物体的长期运行卫星大地测量监测站的数据。

Indication of the impact of increased turbulent activity in the troposphere on the phase measurements of GNSS radio signals (the example of Nadia Hurricane)
The authors examine the impact of Nadia Hurricane, 2022, January, 29–30, over the southern coast of the Baltic Sea, on phase measurements of permanent GNSS stations. For this purpose, the data were processed in PPP mode from 10 objects located in Poland and the Kaliningrad oblast of the Russian Federation. As a result, residuals were obtained, from which the contribution of multipath, ephemeris errors and those, in clock corrections of navigation satellites, were subtracted. It was found out that the standard deviation of cleaned residuals is a weak indicator of increased turbulent activity caused by the hurricane. However, simple counting the total daily number of large cleaned residuals, normalized to the zenith direction can be an effective indicator for identifying periods of high tropospheric turbulence. It can be used both for remote sensing of rapidly developing weather processes, and in interpreting data from permanently operating satellite geodetic monitoring stations of particularly dangerous and technically complex objects
