Abstract

There are presently in existence several well-established models for the calculation of transmittance through atmospheric gases. One is the low-resolution model called LOWTRAN, developed by AFGL and another is the monochromatic (or laser) model called LZTRAN developed by Science Applications Incorporated. In previously reported work, the present authors developed an analytical method using double exponentials to replace the low resolution gaseous transmittance tables in LOWTRAN. In the present work, the authors propose to replace the polynomial functions in LZTRAN with double exponentials, accounting also for atmospheric pressure varia-tions not originally included in this code. The proposed method was tested at 6 laser frequencies for a mixture of absorbers within the bottom 5 km of the atmosphere with a resulting transmittance accuracy of about 3%. The calculations use line-by-line data obtained with the use of the AFGL line-parameter tape.
