Continuous GNSS raw data measured from POLARSTERN deck during the MOSAiC expedition with POLARSTERN to the Arctic on 2020-05-21@en

Raw data acquired by a JAVAD Delta 3 GNSS Receiver with a resolution of 50Hz on board RV Polarstern during the MOSAiC expedition. The data is stored in JAVAD's .jps format (JAVAD GNSS, GREIS – GNSS Receiver External Interface Specification, San Jose, USA, 2022 (download available at https://www.javad.com/jgnss/support/manuals.html)). Each file contains data of one day with a typical file size of 1GB. The receiver was equipped with a multi-frequency GNSS antenna which was mounted on the ship's observation deck. It has to be noted that the main mast and the ship's chimney lead to a shadowing of GNSS observation links in at least two directions seen from the antenna position. The data was collected for measuring scintillation activitiy in the central arctic. Processed scintillation measurements with a 1 minute resolution are available (doi:10.1594/PANGAEA.956019).本数据集源自搭载于北极星号科考船（RV Polarstern）的JAVAD Delta 3型全球导航卫星系统（GNSS）接收机，在MOSAiC科考任务期间采集的原始数据，采样分辨率达50Hz。 数据以JAVAD专属的.jps格式存储（JAVAD GNSS, 美国圣何塞，《GNSS接收机外部接口规范（GREIS）》，2022年，下载链接：https://www.javad.com/jgnss/support/manuals.html）。每份文件包含单日的观测数据，单文件典型大小约为1GB。 该接收机搭载多频GNSS天线，安装于科考船的观测甲板上。需特别说明：从天线位置观测，科考船的主桅杆与烟囱会对至少两个方向的GNSS观测链路造成信号遮挡。 本次数据采集的目的为监测北极中部区域的电离层闪烁活动。此外，分辨率为1分钟的已处理电离层闪烁观测数据集也已公开（DOI: 10.1594/PANGAEA.956019）。
