Pathfinder Windsock Data

windsock_sol73_th.jpg

windsock_sol73.jpg
This sequence of images shows the Pathfinder upper wind sock on the morning of Sol 73 (September 16). The interval between frames is one second. There is no obvious movement of the sock, indicating little or no wind at this elevation (about 1 meter above the surface). At other times during the mission, deflections of this and two lower wind socks have been used to estimate characteristics of the wind speed boundary layer profile.

windprofile_sol82.jpg
This set of images shows the Pathfinder wind socks on the morning of Sol 82 (September 25). The top frames show the upper and middle sock and the bottom frames show the middle and lower socks. Movement of the lower and middle sock is apparent. Deflections of the three wind socks are used to estimate characteristics of the wind speed boundary layer profile.

windsock_sol80_th.jpg

windsock_sol80_th.jpg 
This set of images shows the Pathfinder upper wind sock during two time periods on the morning of Sol 80 (September 23). The interval between frames within each sequence is one second. There is no obvious movement of the sock, indicating little or no wind at this elevation (about 1 meter above the surface). At other times during the mission, deflections of this and two lower wind socks have been used to estimate characteristics of the wind speed boundary layer profile.

windsock_sol79_th.jpg

windsock_sol79_th.jpg 
This sequence of images shows the Pathfinder upper wind sock on the morning of Sol 79 (September 22). The interval between frames is seven seconds. As in the images posted on the web for Sol 73, there is no obvious movement of the sock, indicating little or no wind at this elevation (about 1 meter above the surface). At other times during the mission, deflections of this and two lower wind socks have been used to estimate characteristics of the wind speed boundary layer profile.
