Global distribution of surface soil organic carbon in urban greenspaces

We compiled a global database of SOC concentration and density in urban greenspaces (SOC-U) (updated to June, 2023) based on literature survey via Web of Science (http://isiknowledge.com), Google Scholar (https://scholar.google.com) and the China National Knowledge Infrastructure (http://www.cnki.net). The keywords ‘soil organic carbon’/ ‘SOC’ and ‘urban greenspaces’/ ‘urban parks’/ ‘urban forests’ / ‘urban lawns’ were used for literature search. Overall, the SOC-U database includes 420 and 155 observations of SOC concentration and density from 246 independent publications, across 257 cities in 52 countries.
