Anemometer lowered at EndX Wind Fence

Back in Sept, the locations of the anemometers up by the EndX wind fence were shown on a sketch.  Today ChrisS help move the Wind_Speed_3 sensor from 12' up to 2' AGL; the horizontal location is within a foot, coord +3,-9.  That height above ground level puts the sensor in the middle of the gap between the bottom of the wind cloth and the ground.  We want to study the wind profile as we move from in the middle behind the cloth to in the gap below the cloth.  We expect it to be higher than behind the cloth but is the velocity actually higher than the free stream wind (Wind_Speed_1)-is it accelerated?  So, we'll see.  Report later after we have some wind in the ~right direction.
