This report describes the airborne meteorological MET data acquisition system developed by the FAA R and D Service for atmospheric sounding in support of research programs in aircraft noise, sonic boom, wake vortices, etc. A discussion of the systems instrumentation, design and data measured by the system is given. The airborne system is capable of measuring ambient temperature, dewpoint, turbulence dissipation rate, turbulence structure coefficients Cv and CT, radio and barometric altitude, airspeed, and winds aloft. The flight and recording profiles are numerous and range from meteorologic contouring of large areas up to 60 square miles to very small areas, points and lines. Because turbulence is a difficult parameter to describe andor measure, an extensive section is given on this subject. A recommendation section which describes system improvements for data recording, wind measurement, temperature measurement in moisture, accelerometers, and instrumentation for atmospheric pollution measurements is included.
