Book Description
The purpose of this report is to provide a set of low energy (0-300 eV) cross sections for use in calculating the photoelectron flux in the terrestrial daytime ionosphere. Also given are data on the neutral particle composition of the upper atmosphere and ionizing electromagnetic radiation from the sun.

Book Description
A first principles scientific model for predicting the spectral radiance from the auroral thermosphere seen by an earthlimb observer is described. This model, and the resulting Auroral Atmospheric Radiance Code (AARC), describe the energy deposition in the thermosphere by primary auroral electrons and the ensuing effects. The latter include electron production and production of nonequilibrium concentrations of vibrationally and electronically excited states, by photochemical means, and by energy transfer. Relaxation of the states by collisions and radiation is described, and the transmission of the infrared radiation emitted from these states is treated. Currently, the model considers four radiators: the nitric oxide vibrational fundamental and first overtone at 2.8 and 5.3 micro the NO+ fundamental at 4.3 mirco, and the CO2 asymmetric- stretch (NU -3 mode) emission at 4.3 micro. The prompt optically optically thin emitters (NO and NO+) are treated in terms of stored, precalculated tables of efficiencies (photons per ion-pair).

Book Description
The possible use of satellite ultraviolet measurements to deduce the ionospheric electron density profile (EDP) on a global basis is discussed. A system concept is considered and analyzed which (a) develops and installs a UV sensor on the DMSP satellite and develops an associated automatic data processing (software) system, (b) utilities optical data together with DMSP electron density and temperature data to deduce the near real-time EDP near the satellite orbital plane, and (c) transmits this EDP data to be used together with ground-based ionosonde data and GPS total electron content data to specify the global EDP for systems users. The ionosonde and total electron content data would increase the EDP data base generated by the UV data and refine the UV based EDP where coincident data existed. This report considers (a) the daytime low to midlatitude ionosphere from 90 to 1000 km, (b) the nighttime midlatitude from about 250 km to 1000km, and (c) the auroral E layer from 90 to about 200 km for undisturbed conditions. The spatial resolution for the daytime and nighttime EDP is at least one vertical profile for each square 500 km on a side and for the auroral E layer at least one vertical profile for each square 50km on a side. Other ionospheric regions were not considered because of frequent occurrence of irregularities or highly variable transport conditions.
