Aerodynamic roughness height for gravel-mantled megaripples, with implications for wind profiles near TARs on Mars

Aerodynamic roughness heights of 1-3 cm were obtained from measured wind profiles collected among fields of gravel-mantled megaripples in the high desert of the Puna region of northwestern Argentina. Roughness height appears to be relatively insensitive to the angle at which the wind was incident up...
