From Macro- to Microscale: A combined modelling approach for near-surface wind flow on Mars at sub-dune length-scales

The processes that initiate and sustain sediment transport which contribute to the modification of aeolian deposits in Mars' low-density atmosphere are still not fully understood despite recent atmospheric modelling. However, detailed microscale wind flow modelling, using Computational Fluid Dy...
