Sea ice cover progression in Hudson Bay 2008-2018

The dataset lists the first day of surface air temperatures above zero degC, the sea ice break-up date (ice concentration falling below 15%), the sea ice freeze-up date (ice concentration above 15%), the length of the open water period (number of days between ice concentration falling below 15%), and the number of melt days (defined as time period of surface air temperatures (SAT) above 0C and ice concentrations above 15%) for the entire Hudson Bay region between 2008 – 201

该数据集详细列出了哈德逊湾区域2008年至201X年间每日地面空气温度首次升至零摄氏度以上的日期、海冰断裂日期（冰浓度降至15%以下）、海冰封冻日期（冰浓度升至15%以上）、开放水域期间长度（冰浓度降至15%以下至升至15%以上的天数差）以及融雪天数（定义为地面空气温度（SAT）高于0°C且冰浓度高于15%的时间段）。
