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

Re: [arts-users] Problem about caculating the impact of winds

Dear Wang, note that using the lookup table may not be your best option for wind retrieval. The reason is that it can only interpolate between the precalculated values. If you calculate the absorption on the fly, the line will be Doppler-shifted, which is exact. You can achieve this by
