资源简介:

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,搭载于极星号(RV Polarstern)科考船,采样分辨率为50Hz,采集工作开展于MOSAiC科考活动期间。该数据以JAVAD专属的.jps格式存储,格式遵循JAVAD GNSS公司发布的《GNSS接收机外部接口规范(GREIS,GNSS Receiver External Interface Specification)》,发布于美国圣何塞,2022年,规范下载链接为https://www.javad.com/jgnss/support/manuals.html。每个文件单日存储一次观测数据,单文件典型容量约为1GB。该接收机配备多频GNSS天线,安装于科考船的观测甲板上。需特别指出,从天线的观测视角出发,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分钟的已处理电离层闪烁观测数据可供获取,其DOI编号为10.1594/PANGAEA.956019。
