The TCAD field program was conducted near Greeley, Colorado during June 1999.
Discontinuities are visible in the data.
A better interpolation method for generating the Cartesian plots is under investigation, but it will only be used for high priority cases. The radar plots currently shown are good for a quick look at the data. Vertical cross-sections are taken along the flight paths for the high priority flights. The cross-sections can have multiple segments. This ability is used to create a cross-section that closely parallels the aircraft flight track.
