Continuous GNSS raw data measured from POLARSTERN deck during the MOSAiC expedition with POLARSTERN to the Arctic on 2020-01-08@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).本数据集的原始数据由JAVAD Delta 3型全球导航卫星系统（GNSS）接收机采集，该接收机采样分辨率为50Hz，搭载于RV Polarstern号科考船，采集时段覆盖MOSAiC科考任务全程。 数据以JAVAD专属的.jps格式存储，格式规范遵循JAVAD GNSS公司发布的《GNSS接收机外部接口规范（GNSS Receiver External Interface Specification，简称GREIS）》（美国圣何塞，2022年；公开下载链接：https://www.javad.com/jgnss/support/manuals.html）。 单文件单日存储数据，典型单文件大小约为1GB。 该接收机搭载多频GNSS天线，安装于科考船观测甲板之上。 需特别说明，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挡。 本次数据采集的目标为测量北极中部区域的电离层闪烁活动。 另有经预处理的1分钟分辨率电离层闪烁测量数据可供获取，其DOI编号为10.1594/PANGAEA.956019。
