The Meteorological Measurement System (MMS) is a proven instrument to measure
accurate, high resolution in situ airborne state measurements. Accurate
measurements of these quantities require judicious choices of sensor locations,
repeated laboratory calibrations, and proper corrections for compressibility,
adiabatic heating and flow distortion.
