Continuous GNSS raw data measured from POLARSTERN deck during the MOSAiC expedition with POLARSTERN to the Arctic on 2020-09-17

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).本数据集的原始数据由搭载于“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，采样分辨率达50Hz，采集工作开展于MOSAiC科考行动期间。数据以JAVAD专属的.jps格式存储（依据JAVAD GNSS发布的《GREIS——GNSS接收机外部接口规范》，美国圣何塞，2022年；下载链接：https://www.javad.com/jgnss/support/manuals.html）。单个数据文件存储单日观测数据，典型文件大小为1GB。该接收机搭载多频GNSS天线，安装于科考船的观测甲板之上。需特别说明的是，从天线安装位置观测，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蔽。本次数据采集的目标为北极中部区域的电离层闪烁活动观测。此外还提供分辨率为1分钟的预处理电离层闪烁测量数据，其DOI编号为10.1594/PANGAEA.956019。
