Continuous GNSS raw data measured from POLARSTERN deck during the MOSAiC expedition with POLARSTERN to the Arctic on 2020-02-13@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).本数据集为MOSAiC科考任务期间，搭载于RV Polarstern号极地科考船上的JAVAD Delta 3型全球导航卫星系统（Global Navigation Satellite System，GNSS）接收机采集的原始数据，采样分辨率达50Hz。 该数据采用JAVAD官方的.jps格式存储，符合JAVAD GNSS发布的GREIS——全球导航卫星系统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）。每个文件存储单日观测数据，典型单文件大小约为1GB。 该接收机搭载多频全球导航卫星系统天线，安装于科考船观测甲板上。需注意的是，从天线位置观测，主桅杆与船舶烟囱会导致至少两个方向的GNSS观测链路出现信号遮挡。 本次数据采集旨在监测北极中部地区的电离层闪烁活动。本数据集同时提供分辨率为1分钟的预处理电离层闪烁测量数据，其数字对象标识符（Digital Object Identifier，DOI）为10.1594/PANGAEA.956019。
