| Zusammenfassung |
| The Telltale is a mechanical anemometer consisting of a lightweight cylinder suspended by
Kevlar fibers that are deflected under the action of wind. The Telltale is mounted on top
of the meteorological (MET) mast at roughly 2 meters height above the surface
[1]. Images taken with the Surface Stereo Imager (SSI) of the Telltale deflection
allows the local wind speed and direction to be quantified at the Phoenix landing
site.
In course of the mission, more than 6000 Telltale observations were made, that allowed
for gaining a detailed picture of the wind regime at the landing site. This allows us to assess
the accuracy of predictions from global climate models, slope wind effects, midnight
temperature turbulence, daily temperature differences and possible temperature inversion
arising from frost formation.
