Dear all, I would be very grateful if you could help spread this information. Our new international master program is recruiting its second round of students now. Amongst other things, it includes an advanced course on radiation and climate that I am teaching, and that uses ARTS for the

Kristineberg ARTS workshop 2024, register now

Dear all, summer 2024 is drawing closer, and so is the highlight of this summer, the ARTS radiative transfer workshop at Kristineberg research station, on the Swedish west coast. The workshop will be on June 4-7, 2024 (from noon to noon). The target audience are users and developers of the

3D MC

Dear all, I stumbled accross this interesting paper on an open C library for particularly efficient MC calculations. Could this be the basis of ARTS 3D MC flux and heating rate calculations? Using MC sampling also for the spectral dimension, to be efficient, as in the second paper, which is

Kristineberg 2024

Dear all, just a heads-up: we are planning a radiative transfer workshop next summer (June 4-7, 2024, from noon to noon) in Kristineberg, at the Swedish west coast. The target audience are users and developers of the atmospheric radiative transfer simulator ARTS, and also anyone interested in

Re: ReadHITRAN

Dear Patrick, I think we should put ARTS’ own line catalog in the center wherever possible (which is based on converted current HITRAN). Use it, if you are happy with the parameters there. If you want other parameters, and there is a good reason for that, consider updating it. We have a

Re: VMRs

You are right, the cross dependence would still be there, and come through the dry pressure, which gets smaller when there is more water vapor. Overall, I also still like the option to rescale the VMRs better. /Stefan On 16 Sep 2021, at 21:34, Patrick Eriksson wrote: > Stefan, > >>> For HSE

Dear Stuart, yes, exactly, thanks for pointing this out. :-) I had completely forgotten about this. This problem is related but slightly different: The VMR profile that we get as input may be based on the convention that x = p_species/p_dry, rather than p_species/p_total. I just quickly
