Aerothermal Turbulence Data

DESCRIPTION:

This data is collected by a hot wire probe extended from an aircraft flying at a constant altitude at a constant speed. The current in the wire is proportional to temperature, so the series of measurements is indirecetly related to temperature. The analog voltage data was sampled at 12 KHz and fed through a highpass fourth order Butterworth filter with a cutoff frequency around 0.001 Hz to eliminate the DC bias. The aero dataset is thus the AC voltage (proportional to temperature) with a spatial resolution of approximately 2 cm.
