Dear Satya, the model can run where you have spectroscopic data. So if you use HITRAN (there is a version in ARTS format in the package arts-xml-data, but ARTS also reads the original format directly) you can do calculations in the NIR. But note that the standard HITRAN catalog does not yet include broadening gases other than “air”, so the line widths will not be accurate for Venus. You could investigate what is available from them, though, since they are adding more and more nonstandard parameters.
The more fundamental limitation is that ARTS so far does not allow to include the sun, so you can do only nighttime RT simulations in the NIR for now. (We are working on changing this, but it will take quite some time still). So, the short summary of this is: If you are happy with a nighttime-only simulation with only approximate line-widths, then just switch the line catalog to HITRAN (either ARTS own version or the original) and you should be ok.
