Okhotsk Soya sea ice observation dataset in 2013

This dataset was obtained using PV Soya in the southern Sea of Okhotsk in February 2013, in collaboration between Japan Coast Guard and Hokkaido University to monitor the ice conditions associated with the global warming and improve our understanding of sea ice processes. The dataset is composed of the meteorological data (surface air pressure, air temperature, vapor pressure, winds, and longwave and shortwave radiation) recorded on board at an interval of one minute, the ice thickness data measured with a video system, and hourly visual observation records conducted according to the international ASPeCt protocol. The data format is available in the file, named Readme_soya_2013.docx.

本数据集由日本海上保安厅与北海道大学合作，于2013年2月在鄂霍次克海南部海域通过PV Soya采集完成，旨在监测与全球变暖相关的海冰状况，并加深对海冰过程的科学认知。该数据集包含三类核心数据：其一为以1分钟为间隔记录的船载气象数据，涵盖地表气压、气温、水汽压、风场以及长波辐射、短波辐射；其二为通过视频系统测量得到的海冰厚度数据；其三为依据国际ASPeCt协议开展的每小时目视观测记录。数据格式说明可参阅名为Readme_soya_2013.docx的文件。
