Survey Dataset on the Implementation of AGU Data and Software Sharing Policies in Earth and Space Science (2021–2025)

To investigate the implementation of AGU’s data and software sharing policies, this study selected Earth and Space Science (ESS) as the research subject. AGU currently publishes 24 high-impact peer-reviewed journals, including 12 fully OA journals and 12 hybrid OA journals. ESS is a fully OA journal that publishes original research in Earth science, planetary science, and space science. It was selected for two reasons. First, its launch year essentially aligns with the implementation of the AGU Publications Data Policy. Second, the journal particular focuses on research outputs such as key datasets, observational results, research methods, sensors, and algorithms. This study investigated papers published in ESS between 2021 and 2025, covering a total of 1,421 papers (excluding Issue Information). The data and software sharing practices of ESS were assessed through a manual review of Data Availability Statements, Software Availability Statements, data citations, and software citations. The investigation focused on the following aspects: Availability statements: whether the availability statements of each paper includes information on the data, code, and software tools used or generated in the research process. Data citation: whether the datasets used or generated in the study were declared and cited in the availability statements, reference list, and data-related sections of the manuscript. Software citation: whether the software tools used in the study were declared and cited in the availability statements, reference list, and methods section of the manuscript. Each article was manually reviewed and coded according to predefined survey indicators. A binary coding scheme was applied, where “1” indicates the presence of a given indicator and “0” indicates its absence.为调研美国地球物理联盟（AGU）的数据与软件共享政策落实情况，本研究选取《地球与空间科学》（Earth and Space Science, ESS）作为研究对象。美国地球物理联盟目前出版24种高影响力同行评议期刊，包含12种完全开放获取（OA）期刊与12种混合开放获取（OA）期刊。《地球与空间科学》是一份完全开放获取期刊，刊载地球科学、行星科学及空间科学领域的原创研究论文。选取该期刊主要基于两点原因：其一，其创刊年份与美国地球物理联盟出版数据政策的实施时间基本吻合；其二，该期刊尤其侧重关键数据集、观测结果、研究方法、传感器及算法等研究产出。 本研究调研了2021年至2025年间发表于《地球与空间科学》的论文，共计1421篇（不含期次信息）。本研究通过人工审阅数据可用性声明（Data Availability Statements）、软件可用性声明（Software Availability Statements）、数据引用（data citations）及软件引用（software citations），对《地球与空间科学》的数据与软件共享实践情况进行评估。调研重点涵盖以下方面： - 可用性声明：每篇论文的可用性声明是否包含研究过程中使用或产生的数据、代码及软件工具相关信息； - 数据引用：研究中使用或产生的数据集是否在稿件的可用性声明、参考文献列表及数据相关章节中进行了声明与引用； - 软件引用：研究中使用的软件工具是否在稿件的可用性声明、参考文献列表及方法章节中进行了声明与引用。 所有文章均按照预设的调研指标进行人工审阅与编码。本研究采用二元编码方案（binary coding scheme），其中“1”代表某一指标存在，“0”代表该指标缺失。
