Description of SHARC: The Strategic High-Altitude Radiance Code.

Abstract

The Strategic High-Altitude Radiance Code (SHARC) is a new computer code that calculates atmospheric radiation and transmittance for paths from 60 to 300 km altitude in the 2-40 microns spectral region. It models radiation due to NLTE (Non-Local Thermodynamic Equilibrium) molecular emissions. This initial version of SHARC includes the five strongest IR radiators, NO, CO, H sub 2 ), O sub 3, and CO sub 2. This report describes the code and models used to calculate the NLTE molecular populations and the resulting atmospheric radiance. The SHARC Manual is reproduced in the appendix. Keywords: Infrared radiation; Band radiance; Line-by-line; Atmospheric radiance; Mesosphere, Thermosphere.
