Importance of Surface Roughness for the Local Biogeophysical Effects of Deforestation
Winckler, J.; Reick, C. H.; Bright, R. M.; Pongratz, J. (Journal of Geophysical Research: Atmospheres, 2019)Deforestation influences surface properties such as surface roughness, resulting in changes in the surface energy balance and surface temperature. Recent studies suggest that the biogeophysical effects are dominated by ... -
Past and Future Climate Variability Uncertainties in the Global Carbon Budget Using the MPI Grand Ensemble
Loughran, T. F.; Boysen, L.; Bastos, A.; Hartung, K.; Havermann, F.; Li, H.; Nabel, J. E. M. S.; Obermeier, W. A.; Pongratz, J. (Global Biogeochemical Cycles, 2021-08-21)Quantifying the anthropogenic fluxes of CO2 is important to understand the evolution of carbon sink capacities, on which the required strength of our mitigation efforts directly depends. For the historical period, the ... -
Sources of Uncertainty in Regional and Global Terrestrial CO2 Exchange Estimates
Bastos, A.; O'Sullivan, M.; Ciais, P.; Makowski, D.; Sitch, S.; Friedlingstein, P.; Chevallier, F.; Rödenbeck, C.; Pongratz, J.; Luijkx, I. T.; Patra, P. K.; Peylin, P.; Canadell, J. G.; Lauerwald, R.; Li, W.; Smith, N. E.; Peters, W.; Goll, D. S.; Jain, A.K.; Kato, E.; Lienert, S.; Lombardozzi, D. L.; Haverd, V.; Nabel, J. E. M. S.; Poulter, B.; Tian, H.; Walker, A. P.; Zaehle, S. (Global Biogeochemical Cycles, 2020)The Global Carbon Budget 2018 (GCB2018) estimated by the atmospheric CO 2 growth rate, fossil fuel emissions, and modeled (bottom-up) land and ocean fluxes cannot be fully closed, leading to a “budget imbalance,” highlighting ...
