DTATSET_Soil organic matter signature under impervious surfaces

Total soil organic carbon content and stable carbon isotopes and organic matter composition (mean ± standard deviation/ average deviation) of soils under impervious surfaces and surface and subsurface reference soils measured by solid-state 13C nuclear magnetic resonance spectroscopy are listed in IM-data.xlsx. The soil organic carbon content and density data (SOC data.xlsx) of other cities are available through Cambou et al., 2018; Hu et al., 2018; Majidzadeh et al., 2017; Raciti et al., 2012; Wei et al., 2014a; Wei et al., 2014b; Yan et al., 2015.
