Web users may submit simple calculations via the web. Computations are performed in real time on a Pentium II 450 PC platform hosted by the Atmospheric Research Group at the University of Toronto. Calculations are limited to three-gas mixes and will be truncated if they require too many lines or spectral points. Note that recent versions of Netscape do not appear to correctly process these calculation scripts and consequently we no longer support Netscape browsers and advise users to use Microsoft Internet Explorer instead. This tool allows the computation of transmission, absorption coefficient and radiance along a linear path through a laboratory cell of fixed length.
Users can also specify an optional blackbody source function and temperature.
To use the tool, click here . This tool allows the computation of downward radiance and transmission though a plane parallel atmosphere at a specified zenith angle. Optionally, a blackbody source function can also be specified. To use the tool, click here . Figures for thirty-six gases are included as calculated assuming a standard Earth atmosphere and at ground level.
