TD-4's Data-processing Software
Using TD-4's data-processing software, the user can make graphs showing relationships between "altitude and wind direction" and "altitude and wind speed" as well as graphs showing the path of pilot balloon.
The user can make such graphs based on azimuth and elevation data, taken at certain intervals, which are stored as Excel format.
