Latitudinal and altitudinal controls of Titan's dune field morphometry

► Titan's dune field morphometry is correlated to altitude and latitude. ► Dune to interdune ratio and/or interdune sand cover thickness decrease with these parameters. ► The altitudinal trend is probably caused by the waning of the sand supply toward elevated regions. ► The latitudinal trend could result from a gradual increase in dampness with latitude.
