Lin Yu developed with the rest of the Jena Soil Model (JSM) team a novel soil model (Yu et al., 2020a) and they further tested what is the improvement of this new model in comparison to the original one-dimensional soil model of the QUINCY model. Improving the soil modelling is important, since the current models…
Atmospheric carbon dioxide in global soil carbon model evaluations
I published recently a study, where I used atmospheric CO2 observations to evaluate two different soil carbon models, coupled to a land surface model (paper here, FMI science news in English, in Finnish). Heterotrophic respiration is important part of the global carbon cycle, but it’s direct observation is somewhat impossible at global scale. Even at…
QUINCY in a Nutshell
I was working for three years at Max Planck Institute for Biogeochemistry in Jena, Germany in Sönke Zaehle’s group. I was involved in Sönke’s ERC project, where we were developing a new land surface model ‘QUantifying Interactions between terrestrial Nutrient CYcles and the climate system’, QUINCY. Here I want to list some of the main…
Jarmo Mäkelä’s paper on optimizing stomatal conductances
Jarmo Mäkelä was leading the work on a paper1, published in Geophysical Model Development, where six different formulations for stomatal conductance were optimized with a Monte Carlo style approach. This study was done at 10 boreal coniferous sites, where four sites were used only for validation. The point here is to see, whether the optimization…
