Aggregate hierarchy governs the temperature sensitivity and warming legacy of soil greenhouse gas emissions

The original dataset was compiled to document greenhouse gas production rates under different soil aggregate structures, field warming histories, and incubation temperatures. The database contains treatment information and the corresponding mean values and standard deviations of CO2, N2O, and CH4 emission rates measured during laboratory incubation. Each record represents a unique experimental treatment defined by the combination of aggregate structural conditions, field warming treatment, and incubation temperature. The dataset includes the following variables: Treatment Experimental treatment identifier (T-1 to T-8) representing different aggregate structural configurations. Macroaggregate Structural condition of macroaggregates (>250 μm) in the incubation treatment. Aggregate: intact macroaggregates Crushed: mechanically disrupted macroaggregates N.S.: macroaggregates not included in the treatment Microaggregate Structural condition of microaggregates (
