MRDA - A Medium Resolution Data Analysis Code for the HP 2100 Computer

Abstract

This report describes the Medium Resolution Data Analysis Code (MRDA) which is a computer software code developed to run on the HP2100 mini-computer at the Air Force Geophysics Laboratory. The code calculates the atmosphere transmittance of radiation in the 1800-6000/cm range. The code can be used for a variety of paths(horizontal, vertical, downward, to space, etc). The user has the option of using either the 1962 U.S. Standard Model atmosphere or radiosonde data. Because of size restriction on the HP2100, MRDA is dividied into seven overlays. The spectral absorption coefficients, which are calculated from the AFGL compilation of molecular line parameters (HITRAN), are accessed from a data tape. The transmittance calculated for horizontal paths near sea level agree with those calculated with HITRAN, but MRDA tends to overestimate the absorption in the neighborhood of strongly absorbing lines. Some recommendations for further upgrading of the code are given. (Author)
