Book Description
This report investigates the applicability of the standard LOWTRAN atmospheric models to four typical Australian environments and considers the effects to these environments upon the transmission of 3 to 5 um radiation. It is found that the LOWTRAN model atmospheres can be useful in Australian conditions, and advice is given as to the most appropriate models to use depending upon the path and environment conditions. The extent to which model data is used rather than real data will affect the transmittance predictions; the magnitude of this effect is given, indicating that there is particular value in measuring water vapour content (shown to be the most significant meteorological parameter) in the lowest few kilometers through which the path passes. Transmittance as a function of range (and vice versa) is considered for all slant path angles from vertical to horizontal. Graphical results are presented in full as a resource to be consulted given a particular site ad path transmittance prediction requirement. Keywords: Infrared radiation; Atmospheric models; Slant paths; Australia. (JHD).
