Sonde winds vs.
2004 higher-resolution airborne Doppler winds
Mean  radial wind difference (sonde - Doppler) = -1.4 m/s
Mean tangential wind difference (sonde - Doppler) = 0.2 m/s
Mean wind-speed difference (sonde - Doppler) = 0.8 m/s
RMS radial wind difference = 7.3 m/s
RMS tangential wind difference = 6.0 m/s
RMS wind-speed difference = 6.2 m/s
Note:  Nearly all sondes available for comparison were dropped near the eyewall wind max (the toughest location for comparison because of high wind variability.)
