Integrating Fourier-Transform Infrared Spectroscopy (FTIR) into Peatland Carbon Models: From Local to Global Perspective

Principal investigator: Petra Straková
Funding provider: The Czech Science Foundation
Duration: 2025–2027

Project goals: 

To identify Fourier-Transform Infrared Spectroscopy (FTIR) signatures of organic matter quality and decomposition rates in peatlands, and to integrate these into carbon cycle models for improved ecosystem and global carbon flux estimates. Create a global peatland FTIR library for broader future use.

Project description: 

Integrating Fourier-Transform Infrared spectroscopy (FTIR) into ecosystem carbon (C) models may significantly improve our estimates and understanding of C flux dynamics in peatlands. As crucial stores of global soil C, peatlands require precise analysis of C sequestration and emission mechanisms, particularly under the expected impacts of current climate change scenarios and human land use. This project identifies FTIR signatures of organic matter quality and decomposition rate in peatlands, and integrates these into C cycle models at both ecosystem and global scales. By analysing samples from various climates and peatland types, we aim for a comprehensive FTIR-derived collection of chemical indicators, enhancing the prediction of C stock and greenhouse gas flux estimates. Key outcomes include a global peatland FTIR spectral library, and refined ecosystem models capable of predicting C dynamics changes under varying environmental conditions. This effort advances the accuracy of the global C budget, revealing climate responses of peatlands and possibly shaping management strategies.
