Implications of the choice of land surface model schemes and reanalyzes data for initialization in model simulations with WRF to characterize atmospheric dynamics and the effect on black carbon concentrations into the Eurasian Arctic.
Realistic simulation of physical and dynamical processes happening in the Arctic surface and atmosphere, and the interacting feedbacks of these processes is still a challenge for Arctic climate modelers. This is critical when further studies involving for the example transport mechanisms and pathway...
