Abstract:

The final report describes an effort, under the Simulation Program, to understand infrared backgrounds in an auorally-disturbed environment. A large part of this effort has been devoted to the development and use of a code, called ARCTIC, that is suitable for the study and analysis of auroral data. The code inputs a flux spectrum of primary electrons, incident on or in the atmosphere, with a specified magnetic dip angle and a given initial pitch angle distribution, and computes the detailed energy deposition and partition in the atmosphere. Scattering of the primary electrons is provided for in the deposition subroutine by two options one, that allows for the full effects of range variance, gives excellent agreement with observations in nitrogen the other, that is considerably more economical to use, assumes mean scattering only.
