Stocks of Surface Soil Organic Carbon Fractions, Great Plains Region, USA, 2007-2010

This dataset provides estimates of total organic soil carbon (SOC), pyrogenic (PyC), particulate (POC), and other organic soil carbon (OOC) fractions in 473 surface layer soil samples collected from stratified-sampling locations in Colorado, Kansas, New Mexico, and Wyoming, USA. Terrain, climate, soil, fire, and land cover data used to predict and map SOC, PyC, POC, and OOC at 1 km resolution throughout the study region are also included. The estimates were derived using a best random forest regression model and cover the period 2007-05-01 to 2010-10-01.

本数据集包含美国科罗拉多州、堪萨斯州、新墨西哥州及怀俄明州分层采样点位采集的473个表层土壤样本的总有机土壤碳（total organic soil carbon, SOC）、热解有机碳（pyrogenic carbon, PyC）、颗粒有机碳（particulate organic carbon, POC）以及其他有机土壤碳（other organic soil carbon, OOC）组分含量估算值。本数据集还涵盖用于在整个研究区域内以1千米分辨率预测并绘制SOC、PyC、POC及OOC空间分布的地形、气候、土壤、火灾及土地覆盖数据。该估算值基于最优随机森林回归模型生成，时间覆盖范围为2007年5月1日至2010年10月1日。
