From: Aerodynamic roughness of rippled beds under active saltation at Earth-to-Mars atmospheric pressures

Fig. 6

Aerodynamic roughness due to compounded skin friction and bedforms (bedforms) was calculated using the Jia et al. (2023) model2. Aerodynamic roughness due to saltation (saltation) was estimated using the Andreotti (2004) model22 and Eq. (5), along with calibrated values of α and β (Eqs. (8)–(9)).
