Continuous GNSS raw data measured from POLARSTERN deck during the MOSAiC expedition with POLARSTERN to the Arctic on 2019-12-08

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科考任务期间，搭载于极星号（RV Polarstern）科考船的JAVAD Delta 3型全球导航卫星系统（Global Navigation Satellite System, GNSS）接收机采集的原始观测数据，采样分辨率为50Hz。数据以JAVAD专属的.jps格式存储，对应规范为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。每份文件包含单日观测数据，典型文件大小为1GB。该接收机配备多频GNSS天线，安装于科考船的观测甲板。需特别说明的是，从天线所处位置观测，船舶主桅杆与烟囱会在至少两个方向上对GNSS观测链路造成遮挡。本数据集的采集目标为北极中部地区的电离层闪烁活动观测。另有分辨率为1分钟的处理后电离层闪烁测量数据可供获取，其DOI编号为10.1594/PANGAEA.956019。
