 | The DNA Uranium (Oxides) LWIR Review Committee considered the effectiveness of field measurements of the LWIR from uranium oxides produced by (hypothetical) controlled releases of uranium vapor from rockets in the thermosphere. Collated here is the writer's work supporting the committee on atomic and molecular collision aspects of such releases. Included is an essential auxiliary study to (a) understand, in terms of atomic and molecular parameters, coefficients for Ba+ diffusion ... |

| The Natural Background Radiation Module computes the Earth's natural upwelling spectral radiance (from 2 to 5 micrometers) by averaging over paths in an Earth-tangent cone with vertex at each selected altitude. The processes contributing to the radiance are emission from air, Earth's surface, and clouds and reflection of solar radiation from Earth's surface and clouds; attenuation is by molecules and aerosols. The Module integrates ROSCOE-IR models for atmosphere, atmospheric thermal ... |

 | The ROSCOE-Radar ambient atmosphere model has been extensively revised to provide (a) major atmospheric properties and species densities corresponding to either a code-generated or (optional) user-specified latitude- and season-dependent temperature profile below 120-km altitude, (b) an increase from 10 to 19 minor species profiles (0, 0(1d), (a1 triangle g), 0 sub 3, N(4S), N2D), N(2P), NO, NO sub 2, N sub 2 O, CO sub 2, CO, CH sub 4, ... |

|
| Models of the high-altitude debris-energy partition and deposition have been revised for use in ROSCOE-IR. The principal motivation has been to provide for the increase to 23 from 11 species carried in the high-altitude grid chemistry. However, wherever feasible, corrections, improvements, and updating of the models have been incorporated. Section 4 (UV Source Characteristics) and Section 9 (UV Deposition) of Volume 17 have been modified, and Section 7 (Partitioning of ... |

|
| Models of the high-altitude debris-energy partition and deposition have been adopted for use in ROSCOE. The models for the debris-energy partition and heavy-particle source spectra incorporate the work of Crevier and Kilb for the loss-cone and ion-leak particles. The determination of the total (and spectrum of the) UV portion of the kinetic yield remaining after that assigned to all the heavy-particle motion is based on the work of Fajen and ... |

|
| Two preliminary, alternative models of the high-altitude (h > or = 90 km) neutral-particle motion have been adopted for use in ROSCOE. Both models are one-dimensional spherical Lagrangian models and describe the vertical hydrodynamic motion in each geocentric column in an array of perhaps 100 such continuous but independent columns covering the disturbed region of interest. The models (SAIHYD, NRLHYD) describe the motion of a set of either Lagrangian cells ... |

|
| A preliminary model of the ambient atmosphere and ionosphere has been adopted for use in ROSCOE. The model provides at all altitudes all the needed properties of the neutral atmosphere, including a dependence on the solar cycle and the local (apparent) time for altitudes above 120 km. Analytic fit-functions to Myer's minor-species data base provide all the minor neutral species (O, CO2, N, NO, H2O, O2(1 delta g), O3, and ... |
