Abstract : The ability of the bead thermistor currently used in meteorological sounding rockets to measure the ambient kinetic temperature of the environment is examined theoretically. A non-steady state heat transfer environment including forced convection, infrared and solar radiation, compressional heating, lead wire conduction and internal heating is considered, along with normal variations to be expected in this environment. The temperature measurement error is computed, which, when corrected for, should yield ambient temperature values to within plus or minus 2% up to 60 km with the correction accuracy decreasing to plus or minus 3.8% at 65 km. The correction accuracy deteriorates rapidly above 65 km suggesting that either a different type sensing element or a different sounding technique will be necessary for temperature measurement above this level.
