title = "Aerodynamic influences on atomic oxygen sensors from sounding rockets",
abstract = "Over the past several decades, atomic oxygen (ATOX) measurements taken from sounding rocket sensor payloads in the altitude range of 80-140 kilometers have shown marked variability. ATOX data retrieved from the Coupling of Dynamics and Aurora expericments (CODA I \& II) have shown that the data is highly dependent upon rocket orientation. The present study uses steady, three-dimensional numerical simulations consisting of the Direct Simulation Monte Carlo (DSMC) method and the Navier-Stokes equations with first order slip wall boundary conditions (NS-slip) to model the steady state flow field at seven altitudes along the rockets upleg trajectory. Additionally, three separate rocket orientations are carried out for each altitude. The simulations show conclusively that the relative magnitudes of undisturbed versus disturbed ATOX densities are highly dependent on rocket orientation and provide a means of applying {"}correction{"} functions to existing ATOX data sets.",
