To capture the effects of mesoscale turbulent eddies, coarse-resolution Eulerian ocean models resort to tracer diffusion parameterizations. Likewise, the effect of eddy dispersion needs to be parameterized when computing Lagrangian pathways...
Tropical Peatland Hydrology Simulated With a Global Land Surface Model [0.03%]
具有全球陆面模型的热带泥炭地水文学模拟结果
S Apers,G J M De Lannoy,A J Baird et al.
S Apers et al.
Tropical peatlands are among the most carbon-dense ecosystems on Earth, and their water storage dynamics strongly control these carbon stocks. The hydrological functioning of tropical peatlands differs from that of northern peatlands, which...
The Global Atmosphere-aerosol Model ICON-A-HAM2.3-Initial Model Evaluation and Effects of Radiation Balance Tuning on Aerosol Optical Thickness [0.03%]
