Ship-borne radiosonde observation data over the Arctic Ocean in the 2017 Araon summer expedition(ARA08B,ARA08C)

The radiosonde balloon sounding observations were performed from 7 August 2017 to 13 September 2017 to obtain the Arctic Ocean high-resolution atmospheric vertical profiles along the IBRV Araon cruise track at four times daily intervals(00,06,12, and 18UTC). The data include vertical profiles of temperature, humidity, pressure, wind speed, and wind direction up to about 30km. The data have been used for the data assimilation of the KOPRI Arctic weather forecast system.

本数据集为2017年8月7日至2017年9月13日期间开展的无线电探空观测成果，旨在获取北冰洋沿IBRV Araon号科考航迹的高分辨率大气垂直廓线，观测频次为每日4次，对应世界时00、06、12、18时。数据涵盖最高约30千米高度的温度、湿度、气压、风速及风向垂直廓线。该数据集已应用于韩国极地研究所（KOPRI）北极天气预报系统的数据同化工作。
