Transverse aeolian ridges
Transverse aeolian ridges (TAR's) are a type of sand ridge on Mars and are one of the most common landforms on Mars.[1] They are mid-way in height between dunes and ripples; they are not well understood. TAR's are often seen in low places like valley floors. In today's climate on Mars they are not moving. TARs are most common near the equator.[2][3]
The term ‘transverse aeolian ridge’, or ‘TAR’ was first used by M. Bourke et al. in 2003.[4]
