Advancing the modelling of the peatland carbon balance through assimilation of high-resolution component flux and phenology data

Summary

Our project aim is to advance a well-established peatland C cycle model by incorporating high-temporal resolution observations of i) individual net carbon dioxide (CO2) exchange component fluxes and ii) vegetation phenology. The specific objectives are: 1) To obtain novel empirical data on the individual peatland production and respiration component fluxes at high temporal resolution 2) To improve model algorithms for estimating autotrophic and heterotrophic respiration fluxes in boreal peatlands 3) To develop a dynamic vegetation model for improving simulations of peatland gross primary production and allocation to above- and belowground net primary production
