Ka-Band Probe Radar (KPR) measurements of reflectivity, spectral width, and velocity in fixed height 15m bins above msl using a ProSensing 35.6 GHz Ka-band probe radar. No corrections were done to remove ground reflections or other bad data, except for masking out the first 91 meters above and below the aircraft. The approximate height of each radar bin was estimated from the original bin range and the altitude and orientation of the aircraft. The velocity values were not adjusted for the movement nor orientation of the aircraft. The sign of the downward pointing radar velocities was flipped so that positive always refers to up and negative to down with respect to the orientation of the plane. Latitude, longitude, pitch, roll, airspeed, and altitude are also included from the onboard instruments, documented separately https://doi.org/10.26023/GENG-Q8WN-TB13.
