Okhotsk Soya sea ice observation dataset in 2007

This dataset was obtained using PV Soya in the southern Sea of Okhotsk in February 2007, 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_2007.docx.

本数据集于2007年2月在鄂霍次克海南部海域依托PV Soya采集，由日本海上保安厅与北海道大学联合开展，旨在监测与全球变暖相关的海冰状况，并深化对海冰过程的科学认知。该数据集包含三类核心数据：一是以1分钟为采样间隔在船载平台记录的气象数据，涵盖地表气压、气温、水汽压、风场以及长波辐射与短波辐射；二是通过视频系统实测的海冰厚度数据；三是遵循国际ASPeCt协议开展的每小时目视观测记录。数据格式及相关说明可参阅名为Readme_soya_2007.docx的文件。
