Short summary

Global soil heterotrophic respiration (RH) was modelled using Random Forest by linking published observations and globally gridded environmental variables. Globally, RH increased from 55.8 to 58.3 Pg C a⁻¹ with an increasing trend of 0.036 ± 0.007 Pg C a⁻² and an annual mean RH of 57.2 ± 0.6 Pg C a⁻¹ over 1980–2016. The developed RH dataset has great potential to serve as a benchmark to constrain global vegetation models.
