Short summary
We present a method to estimate the degree of decomposition (fraction of initial mass remaining) of peat from mid-infrared spectra, which also allows to reconstruct the initial mass (aboveground net primary production). Both quantities are required to estimate the mass and carbon balance of peatlands and are useful to model peat physical and hydraulic properties. The approach is therefore useful to test and improve peatland models and our understanding of the long-term peatland carbon cycle.
