Transmissivity spectrum of water vapor

[rese_support]

I want to see the transmissivity spectrum at a given level of wate vapor content. 

Does modo have this function? 

This can be done in transmittance mode and by setting the columnar water vapor amount in card 1a - you need the full Modtran interface (Generate Tape5) for that, the parameter is on line 3 of the GUI; please refer to the modtran manual page 16 to see the options as of how to enter the parameter H2OSTR .
