Continuous GNSS raw data measured from POLARSTERN deck during the MOSAiC expedition with POLARSTERN to the Arctic on 2019-12-10@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).本数据集为MOSAiC北极科考航次期间，搭载于“极星号”（RV Polarstern）科考船的JAVAD Delta 3型全球导航卫星系统（GNSS）接收机采集的原始观测数据，采样率为50Hz。数据以JAVAD专用的.jps格式存储，相关规范参考《GREIS——全球导航卫星系统接收机外部接口规范》（JAVAD GNSS，美国圣何塞，2022年，下载链接：https://www.javad.com/jgnss/support/manuals.html）。每个文件存储单日的完整观测数据，单文件典型大小约为1GB。该接收机搭载多频GNSS天线，安装于科考船观测甲板。需特别说明：从天线安装位置观测，科考船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。本次数据采集旨在开展北极中心区域的电离层闪烁活动观测。配套的1分钟分辨率电离层闪烁处理后数据集已公开，其DOI编号为10.1594/PANGAEA.956019。
