description abstract	Description of Driving Event: The ability to measure from an airborne platform turbulence in the daytime convective planetary boundary layer has existed for several years. The accuracy of these measurements is, in many cases, limited by the errors in the air velocity measurements. current measurement techniques are typically limited by: • Measurements of ambient air flow made in relatively close proximity to the aircraft and therefore influenced by the flow around the aircraft. • A total "system calibration" that is not based on physical constants. • An inability to make reliable measurements in clouds and in precipitation. • Mechanical resonances of the aircraft which may have a detrimental influence on the data quality.
