Earliest snowmelt estimation dates for Arctic sea ice (2003)

Earliest snowmelt estimation dates calculated for the year 2003 are provided using sea ice brightness temperatures from AMSR-E (Cavalieri et al., 2014) and DMSP SSM/I-SSMIS (Meier et al., 2019), as well as simulated sea ice brightness temperatures from the CESM2 JRA-55 (Danabasoglu et al., 2020; Kobayashi et al., 2015; Tsujino et al., 2018), which were created using the Arctic Ocean Observation Operator (ARC3O; Burgard et al, 2020a,b). Scripts and README files are provided for preparing the model data to act as input to ARC3O.本数据集提供了针对2003年计算得到的最早融雪估算日期，其计算所用数据涵盖：来自高级微波扫描辐射计-地球观测系统（AMSR-E，Cavalieri等，2014）与国防气象卫星计划专用微波成像仪/专用微波扫描成像辐射计（DMSP SSM/I-SSMIS，Meier等，2019）的海冰亮温，以及来自社区地球系统模型2 日本55年再分析数据集（CESM2 JRA-55，Danabasoglu等，2020；Kobayashi等，2015；Tsujino等，2018）的模拟海冰亮温；上述模拟海冰亮温数据均通过北极海洋观测算子（ARC3O，Burgard等，2020a,b）生成。此外，本数据集还附带用于将模型数据预处理为ARC3O输入格式的脚本与README文档。
