Model run with METROMS to evaluate open boundary conditions in CICE

Support for time-varying open boundary conditions (OBC) have been developed for sea ice in the Los Alamos Sea Ice Model (CICE) by Pedro Duarte (NPI, Norway). This dataset is a result of using the coupled ocean (ROMS) and sea ice (CICE) modelling framework METROMS (https://github.com/metno/metroms) in order to test the effects of the above mentioned boundary conditions. The specific application of METROMS that was used was MET Norway's main forecasting system for the Barents Sea; the Barents-2.5km model; details about the model can be found at https://ocean.met.no/models.

The model was initialized from the TOPAZ4 model (Sakov et al., 2012) and was run for the period 2019.09.01 - 2019.10.03, one time without OBC and one time with OBC enabled using input data from TOPAZ4 at the boundaries. This dataset can further be used to compare with satelite observations of sea ice concentration in order to help evaluate the impacts of the OBC's in CICE.

挪威极地研究所（Norwegian Polar Institute, NPI）的Pedro Duarte为洛斯阿拉莫斯海冰模式（Los Alamos Sea Ice Model, CICE）开发了时变开边界条件（Open Boundary Conditions, OBC）的支持功能。本数据集依托耦合海洋模式（ROMS）与海冰模式（CICE）的建模框架METROMS（https://github.com/metno/metroms）构建，用于测试上述开边界条件的影响效果。本次所用的METROMS具体为挪威气象研究所（MET Norway）针对巴伦支海的核心业务预报系统——巴伦支海2.5公里分辨率模式（Barents-2.5km model），该模式的详细信息可通过https://ocean.met.no/models查询。

该模式以TOPAZ4模式（Sakov等，2012）为初始场，模拟时段为2019年9月1日至2019年10月3日，共设置两组对照试验：一组未启用开边界条件，另一组以TOPAZ4的边界输入数据启用开边界条件。本数据集可进一步与海冰密集度的卫星观测数据开展对比分析，以辅助评估CICE中开边界条件的影响效果。
