Soil organic carbon distribution for 0-3 m soils at 1 km2 scale of the frozen ground in the Third Pole Regions

<p>Soil organic carbon (SOC) is very important in the vulnerable ecological environment of the Third Pole; however, data regarding the spatial distribution of SOC are still scarce and uncertain. Based on multiple environmental variables and soil profile data from 458 pits (depth of 0&ndash;1 m) and 114 cores (depth of 0&ndash;3 m), this study uses a machine-learning approach to evaluate the SOC storage and spatial distribution at different soil depths (0&ndash;30 cm, 0&ndash;50 cm, 0&ndash;100 cm, 0&ndash;200 cm, and 0&ndash;300 cm) in the frozen ground area of the Third Pole region. Our results provide information on the storage, patterns, and environmental controls of SOCSs at a 1 km² scale for areas of frozen ground in the Third Pole region, thus providing a scientific basis for future studies pertaining to Earth system models.</p> <p>Soil organic carbon data is stored in grids format, and the file name is &quot;TP-SOC-d.tif&quot;, where d represents soil depth, for example, &quot;TP-SOC-30.tif&quot; represents the spatial distribution of soil organic carbon stocks in the Third Pole regions of the upper 30 cm depth interval.</p> <p>&nbsp;</p>
