Description This dataset covers pan-European areas, including Ukraine, the UK, and Turkey. This data cube could be used for applications such as soil property mapping and comprehensive soil health assessment across Europe. The dataset spans four depth ranges and multiple time periods, providing information for studies on soil organic carbon stock and dynamics. This dataset is part of the Spatiotemporal prediction of soil organic carbon density for Europe (2000-2022) in 3D+T dataset. Check the related identifiers section below to access other parts of the dataset. This data set includes: Soil Organic Carbon Density (SOCD) (2000-2022, 4-year intervals): This data includes mean, p975, and p025 SOCD maps for four depth ranges (0-20cm, 20-50cm, 50-100cm, and 100-200cm) in kg/m3 (scaled 10x).

The convention works with 10 fields that describe important properties of the data. In this way users can search files, prepare data analysis etc, without needing to open files. The fields are: generic variable name: oc = organic carbon variable procedure combination: iso.10694.1995.mg.cm3 = ISO method 10694:1995, with values in mg/cm3 for SOCD | iso.10694.1995.wpct = ISO method 10694:1995, with values in weighted percentage of organic carbon content. Position in the probability distribution/variable type: m = mean | p975 = percentile 97.5 | p025 = percentile 2.5 Spatial support: 30m Depth reference: b0cm..20cm = depth range from 0 to 20cm Time reference begin time: 20000101 = 2000-01-01 Time reference end time: 20041231 = 2004-12-31 Bounding box: eu = pan-Europe EPSG code: epsg.3035 Version code: v20240804 = version from 2024-08-04子数据集：土壤有机碳密度（Soil Organic Carbon Density, SOCD）p975，2016–2020 ## 免责声明 本数据集为泛欧土壤健康指标（Soil Health Indicators）预测成果的首次发布（即土壤健康数据立方体(Soil Health Data Cube)），仅可用于测试用途。描述所用方法的相关论文已提交至《PeerJ》期刊并处于审稿阶段。本项目由欧盟资助，文中观点仅代表作者本人，未必反映欧盟或欧洲委员会的立场。欧盟及相关授权机构不对本数据集的使用承担任何责任，数据以“现状”提供。AI4SoilHealth项目联盟及其供应商、许可方特此声明放弃所有明示或默示的担保，包括但不限于适销性、特定用途适用性以及不侵权的担保。AI4SoilHealth项目联盟及其供应商、许可方均不保证本网站无错误、访问持续或不间断。您理解通过本网站下载或以其他方式获取内容或服务均出于您的自主判断，风险由您自行承担。 ## 数据集说明 本数据集覆盖泛欧区域，包括乌克兰、英国及土耳其。该数据立方体可用于欧洲范围内的土壤属性制图、全面土壤健康评估等应用。数据集涵盖四类深度区间与多个时间周期，可为土壤有机碳储量及其动态变化的相关研究提供数据支撑。 本数据集属于“欧洲土壤有机碳密度时空预测（2000-2022）三维时空（3D+T）数据集”的组成部分，请参阅下文相关标识符板块以获取数据集的其他部分。 本数据集包含以下内容： 1. 土壤有机碳密度（Soil Organic Carbon Density, SOCD）（2000-2022，每4年一个时间间隔）： 该数据包含四类深度区间（0-20cm、20-50cm、50-100cm、100-200cm）的SOCD均值、p975分位数与p025分位数图，单位为kg/m³（已按10倍缩放）。 2. 基于干式燃烧法的有机碳质量分数（Weight Percentage, WPCT）（2000-2022，每4年一个时间间隔）： 该数据包含四类深度区间（0-20cm、20-50cm、50-100cm、100-200cm）的有机碳质量分数均值、p975分位数与p025分位数图，单位为百分比（已按10倍缩放）。 ## 相关标识符 - SOCD均值：2000-2004、2004-2008、2008-2012、2012-2016、2016-2020、2020-2022 - SOCD p025分位数：2000-2004、2004-2008、2008-2012、2012-2016、2016-2020、2020-2022 - SOCD p975分位数：2000-2004、2004-2008、2008-2012、2012-2016、2016-2020、2020-2022 ## 数据详情 - 时间周期：2000–2022，每4年为一个间隔（最后一个周期覆盖2020–2022）。 - 数据类型：时空型土壤有机碳数据立方体，包含土壤碳评估所需的深度区间与质量分数数据。 - 数据采集/衍生方式：本数据通过机器学习模型衍生得到。 - 所用统计方法：分位数随机森林（Quantile Random Forest） - 数据局限性与排除范围：本数据集未包含斯瓦尔巴群岛的相关数据。 - 坐标参考系统：EPSG:3035 - 边界框（Xmin, Ymin, Xmax, Ymax）：(900000, 899000, 7401000, 5501000) - 空间分辨率：30m - 图像尺寸：216700像素 × 153400行 - 文件格式：云优化GeoTIFF（Cloud Optimized Geotiff, COG）格式。 ## 技术支持 若您发现漏洞、异常或不一致之处，或有相关疑问，请提交GitLab Issues（待确认）：GitLab Issues (tbc) ## 命名规范 为确保项目内与跨项目的一致性和易用性，本数据集遵循AI4SoilHealth与Open-Earth-Monitor的标准文件命名约定。该约定包含10个字段，用于描述数据的关键属性，使用户无需打开文件即可搜索文件、开展数据分析等工作。各字段说明如下： 1. 通用变量名：oc = 有机碳 2. 变量-处理方法组合：iso.10694.1995.mg.cm3 = 符合ISO 10694:1995标准，SOCD单位为mg/cm³ | iso.10694.1995.wpct = 符合ISO 10694:1995标准，有机碳含量以质量分数计 3. 概率分布位置/变量类型：m = 均值 | p975 = 97.5分位数 | p025 = 2.5分位数 4. 空间支撑：30m 5. 深度参考：b0cm..20cm = 0至20cm的深度区间 6. 时间参考起始时间：20000101 = 2000-01-01 7. 时间参考结束时间：20041231 = 2004-12-31 8. 边界框：eu = 泛欧区域 9.
