Continuous GNSS raw data measured from POLARSTERN deck during the MOSAiC expedition with POLARSTERN to the Arctic on 2020-04-06@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采集自"MOSAiC"科考任务期间，搭载于"Polarstern"号科考船（RV Polarstern）的JAVAD Delta 3型全球导航卫星系统（GNSS, Global Navigation Satellite System）接收机，该接收机的采样分辨率为50Hz。该数据以JAVAD官方的.jps格式存储，相关格式规范参见《GREIS——GNSS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）。单个数据文件对应单日观测数据，典型文件大小约为1GB。该接收机搭载多频GNSS天线，天线安装于科考船的观测甲板上。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挡。本次数据采集旨在开展北极中部区域的电离层闪烁活动观测。另有经预处理的、分辨率为1分钟的电离层闪烁测量数据公开可用，其DOI编号为10.1594/PANGAEA.956019。
