Abstract
Sediment suspension is a common and important phenomenon in planetary atmospheres. A widely‐used suspension criterion, also a proxy boundary layer wind‐speed indicator, was discredited by Mars Exploration Rover Mission results concerning sediment particle sizes in active surface bed forms. Parameterisation of a new dynamic suspension criterion based upon turbulent stress yields predicted suspension threshold conditions consistent with those inferred for Earth and predicts no suspension of sand‐grade particles for recent Martian wind velocities (at 1m height) estimated in the range 28–73 m s−1. Results for Venus imply suspension of very fine sand particles at low surface wind speeds.
