Lake ice safety data

This repository includes data from the Community Earth System Model Version 2 Large Ensemble (CESM2-LE) and the necessary code to process the data. The code uses the downloaded CESM2-LE data to detect periods of unsafe ice cover throughout the Northern Hemisphere at different warming scenarios as well as ice quality (i.e., black ice:white ice ratios) scenarios.The model output of CESM2LE is available via: https://www.cesm.ucar.edu/projects/communityprojects/LENS2/data-sets.html.There is also a validation component. Because not all of those data are publicly available, we have included information to access those data from the studies that used the data originally within the GitHub repository. For access locations of all validation data, please see the "#2 Import Data" section script "01_ice_thickness_validation.R". It provides all DOIs to download or request the necessary CSV files.All code to reproduce the research is available at: https://github.com/jculpepper7/ice_safety_2024This work us currently under review at PLOS ONE and will be updated if there are any changes.

本仓库涵盖社区地球系统模型版本2大集合（Community Earth System Model Version 2 Large Ensemble，CESM2-LE）的相关数据，以及用于处理该数据的配套代码。该代码依托已下载的CESM2-LE数据，可检测不同增温情景下北半球全域的不安全冰覆盖时段，同时可分析冰体质量情景（即黑冰与白冰的占比）。CESM2LE的模型输出可通过以下链接获取：https://www.cesm.ucar.edu/projects/communityprojects/LENS2/data-sets.html。本仓库还包含验证模块。由于部分数据并未公开，我们已在该GitHub仓库中提供了从原始使用该数据的研究中获取这些数据的相关指引。若需获取所有验证数据的访问途径，请参阅脚本"01_ice_thickness_validation.R"中的"#2 Import Data"章节，该章节提供了所有用于下载或申请所需CSV文件的数字对象标识符（DOI）。所有可复现本研究的代码均可通过以下链接获取：https://github.com/jculpepper7/ice_safety_2024。本研究目前正在《PLOS ONE》期刊送审，如有任何变更将同步更新。
