The Arctic region is one of the most sensitive regions to global climate change in terms of response and feedback. Sea ice in the Arctic region affects the Arctic environment, ecosystems, and climate while also exerting profound influences on global ocean circulation, climate, and biodiversity. Hence, gaining a deep understanding of sea ice is critical for understanding the operational mechanisms of the Earth system, predicting climate change trends, conserving ecosystems, and advancing sustainable development. Through remote sensing observations and numerical simulations, substantial scientific data related to the historical distribution and future changes of Arctic sea ice have been acquired. These data are currently stored in large remote sensing science data centers and multiple Earth system simulation data centers involved in the Coupled Model Intercomparison Project (CMIP). However, a thorough comparative analysis of these distributed scientific data is challenged by the downloading of mass data. Based on the CMIP scientific data, this study demonstrated the difficulties encountered in data downloading. Accordingly, this study proposed a novel method and corresponding software solution for online collaborative analysis. Focusing on the sea ice data from remote sensing observations and numerical simulations, this study expounded the deployment and operation of the proposed method in multiple institutions. The proposed method can enrich the technical system for the findability, accessibility, interoperability, and reusability of the scientific data of sea ice. The demonstrated online collaborative analysis system can significantly enhance the analysis and utilization efficiency of sea ice data.
