Alexandra Pongracz is a PhD student at the Department of Physical Geography and Ecosystem Science at Lund University. Her research project investigates the impact of winter warming on the arctic carbon cycling. She is using and developing the LPJ-GUESS dynamics vegetation model, focusing on cold season processes and soil-snow-vegetation interactions.
Her presentation at EGU22 highlighted the importance of accounting for non-growing season processes in ecosystem models. Alexandra introduced the performance of a new snow scheme in LPJ-GUESS, which improved the simulation of permafrost extent and near-surface soil temperatures. She aims to evaluate the future high latitude carbon balance under different climate scenarios, utilising the recent model developments.
