    Above are shown point-by-point Wind Speed (top) and Wind Direction (bottom) values obtained from Surface Stereographic Imager (SSI) imaging the Telltale Wind Sensor onboard the Mars Phoenix Lander during sols 1-30 of that mission's 151 sol duration.

    The Wind Speed and Direction values plotted above are available within the TELLTALE_01_30.TAB ASCII Derived Data collection. The contents of the TELLTALE_01_30.TAB file and a description of the structure of that file are available in the TELLTALE_01_30.XML file which is also located within the Derived Data collection. Wind speed and direction values for mission sols 31-90 are available in the TELLTALE_31_90.TAB ASCII file and the sols 91-151 wind speed and direction values are available within the TELLTALE_91-151.TAB ASCII file also located within the Derived Data collection.

    Telltale Anemometer (TT)
    Throughout the course of Phoenix surface operations, the Surface Stereoscopic Imager (SSI) took images of the Telltale Anemometer. The Telltale device consisted of a suspended weight that was free to move in the wind. Precise imaging of the device could allow wind speeds and directions to be calculated at the time of the image.
