Large eddy simulations of the Martian convective boundary layer: Towards developing a new planetary boundary layer scheme

The grid resolutions typically employed in atmospheric global circulation and mesoscale models are not sufficient to explicitly resolve the turbulence processes within planetary boundary layer (PBL). turbulent fluxes are, therefore, fully parameterized those models, based on empirical relationships for mixing length scale using PBL schemes. However, microscale use large-eddy simulation (LES) technique processes. Here, we perform LES computations daytime Martian layer, ranging from weakly strong convective conditions, Mars implementation of planetWRF, MarsWRF model. In this study, our main focus is investigate statistics spectrum utilizing results. Then, computed kinetic energy its dissipation rate, a generic formulation variation proposed. This used derive Mars-specific scheme performance compared currently by model, MRF scheme. proposed tested both simulations, which evaluate height near-surface meteorology conditions at InSight landing site. presently results an improved prediction that agree better with observational estimations acquired radio occultations Express comparison Also, winds site slightly improved.
