Continuous GNSS raw data measured from POLARSTERN deck during the MOSAiC expedition with POLARSTERN to the Arctic on 2020-05-04

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RV Polarstern（极星号）科考船的JAVAD Delta 3型全球导航卫星系统（GNSS）接收机采集，采样分辨率为50Hz，采集工作开展于MOSAiC科考航次。数据以JAVAD专属的.jps格式存储，相关规范为美国圣何塞的JAVAD GNSS公司于2022年发布的《GNSS接收机外部接口规范（GREIS – GNSS Receiver External Interface Specification）》，规范下载链接为https://www.javad.com/jgnss/support/manuals.html。每份文件存储单日观测数据，典型文件大小约为1GB。该接收机搭载多频GNSS天线，安装于科考船的观测甲板上。需特别说明的是，从天线安装位置观察，主桅杆与船用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。此外，分辨率为1分钟的预处理电离层闪烁测量数据已可获取，其数字对象标识符（DOI）为10.1594/PANGAEA.956019。
