Okhotsk Soya sea ice observation dataset in 2012

This dataset was obtained using PV Soya in the southern Sea of Okhotsk in February 2012, 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_2012.docx.

本数据集由日本海上保安厅（Japan Coast Guard）与北海道大学（Hokkaido University）合作，于2012年2月在鄂霍次克海南部海域依托PV Soya获取，旨在监测与全球变暖相关的海冰状况，加深对海冰过程的理解。该数据集包含三类数据：其一为以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、风速以及长波辐射与短波辐射；其二为通过视频系统测得的海冰厚度数据；其三为依照国际ASPeCt协议开展的每小时目视观测记录。相关数据格式说明可参阅名为Readme_soya_2012.docx的文档。
