Excited to share our latest publication in @natcomms.nature.com, where we analyze the aerodynamic roughness length over equilibrated rippled sand beds with active saltation under atmospheric pressures intermediate between those of Earth and Mars. www.nature.com/articles/s41...

Aerodynamic roughness of rippled beds under active saltation at Earth-to-Mars atmospheric pressures - Nature Communications Low-pressure wind tunnel experiments suggest that the aerodynamic roughness length on Mars, over rippled beds and under active saltation, may be dominated by form drag, reaching values up to two order... https://www.nature.com/articles/s41467-025-60212-7?utm_source=rct_congratemailt&utm_medium=email&utm_campaign=oa_20250602&utm_content=10.1038/s41467-025-60212-7
