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.

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：土壤有机碳密度均值（Soil Organic Carbon Density, SOCD m），2008–2012年 免责声明 本数据集为泛欧土壤健康指标预测（土壤健康数据立方体）的首次发布版本，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（European Union）资助，然文中所表达的观点仅代表作者本人，未必反映欧盟或欧洲委员会（European Commission）的立场。欧盟及资助机构不对本数据集的使用承担任何责任。本数据集按“现状”提供。AI4SoilHealth项目联盟及其供应商与授权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与授权方亦不保证本网站无错误、或其访问可连续且不间断。您应知悉，从本网站下载或以其他方式获取内容或服务均需自行承担风险与判断。 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。本数据立方体可用于欧洲范围内的土壤属性制图与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段，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“2000–2022年欧洲土壤有机碳密度时空预测（3D+T数据集）”的组成部分。请查阅下文相关标识符章节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年，每4年一个时段）： 本数据包含四类深度区间（0–20cm、20–50cm、50–100cm及100–200cm）的SOCD均值、97.5百分位数（p975）与2.5百分位数（p025）分布图，单位为kg/m³。 2. 基于干式燃烧重量百分比的有机碳含量（WPCT）（2000–2022年，每4年一个时段）： 本数据包含四类深度区间（0–20cm、20–50cm、50–100cm及100–200cm）的WPCT均值、97.5百分位数（p975）与2.5百分位数（p025）分布图，单位为g/kg。 相关标识符 SOCD均值：2000–2004、2004–2008、2008–2012、2012–2016、2016–2020、2020–2022 SOCD 2.5百分位数：2000–2004、2004–2008、2008–2012、2012–2016、2016–2020、2020–2022 SOCD 97.5百分位数：2000–2004、2004–2008、2008–2012、2012–2016、2016–2020、2020–2022 数据详情 时间范围：2000–2022年，以4年为间隔（最后一个时段覆盖2020–2022年）。 数据类型：时空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重量百分比数据。 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：随机森林（Random Forest） 数据局限性与排除项：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（X最小值、Y最小值、X最大值、Y最大值）：(900000, 899000, 7401000, 5501000) 空间分辨率：30米 图像尺寸：216700列 × 153400行 文件格式：云优化地理Tiff（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）工单。 命名规范 为确保项目内外的一致性与易用性，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，使用户可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，有机碳含量以重量百分比计。 3. 概率分布位置/变量类型：m = 均值；p975 = 97.5百分位数；p025 = 2.5百分位数 4. 空间支撑：30m 5. 深度参考：b0cm..20cm = 深度区间为0至20厘米 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.
