Datasets of ionospheric parameters provided by SCINDA GNSS receiver from Lisbon airport area

Here we present datasets provided by a SCINDA GNSS receiver installed in Lisbon airport area from November of 2014 to July of 2019. The installed equipment is a NovAtel EURO4 with a JAVAD Choke-Ring antenna. The data are in the archived format and include the general messages on quality of records (*.msg), random number generator files (*.rng), raw observables as the signal-to-noise (S/N) ratios, pseudoranges and phases (*.obs), receiver position information (*.psn), ionosphere scintillations monitor (*.ism) and ionospheric parameters: total electron content, TEC, rate of change of TEC, ROTI, and the scintillation index S4 (*.scn). The presented data cover the full 2015 year. The raw data are of 1-minute resolution and available for each of receiver-satellite pairs. The processing and the analysis of the ionosphere scintillation datasets can be done using a dedicated "SCINDA-Iono" toolbox for MATLAB developed by T. Barlyaeva (2019) and available online via MathWorks File Exchange system. The toolbox allows to calculate 1-hour means for ionospheric parameters both for each of available receiver-satellite pairs and averaged over all available satellites during the analyzed hour. Here we present also the processed data for the following months in 2015: March, June, October, and December. The months were selected as containing most significant geomagnetic events of 2015. The 1-hour means for other months can be obtained from the raw data using, e.g. the aforementioned toolbox. The provided datasets can be of interest for the GNSS and ionosphere scientific communities.

本报告展示自2014年11月至2019年7月间，在里斯本机场区域安装的SCINDA GNSS接收器所提供的数据集。该设备为NovAtel EURO4型，配备JAVAD Choke-Ring天线。数据以存档格式存储，包含关于记录质量的一般消息（*.msg）、随机数生成文件（*.rng）、包含信号噪声比（S/N）、伪距和相位（*.obs）的原始观测值、接收机位置信息（*.psn）、电离层闪烁监测（*.ism）以及电离层参数：总电子含量（TEC）、TEC变化率（ROTI）、闪烁指数S4（*.scn）。所提供数据覆盖了2015年全年。原始数据具有每分钟一分钟的分辨率，并针对每对接收机-卫星组合提供。电离层闪烁数据集的处理与分析可通过T. Barlyaeva（2019）开发的专用“SCINDA-Iono”MATLAB工具箱完成，该工具箱可通过MathWorks文件交换系统在线获取。该工具箱允许计算每个可用接收机-卫星对以及分析小时内所有可用卫星的平均电离层参数的1小时平均值。此外，本报告还展示了2015年3月、6月、10月和12月的处理数据，这些月份被选为包含2015年最具显著性地球物理事件的时间。其他月份的1小时平均值可通过使用上述工具箱从原始数据中获取。所提供的数据集对于GNSS和电离层科学界可能具有研究价值。
