Hi Freddy,
Thank you so much and this is very helpful! Just to make sure I fully
understand how to use it in the code -- According to ARTS output, it
seems I need to provide the skin temperature as well. I noticed that
in one provided example it has "
ws.ArrayOfStringSet(ws.surface_props_names, ["Skin temperature"])
ws.Tensor3SetConstant(ws.surface_props_data, 1, nlat, nlon,
ws.t_field.value[0, 0, 0])"
I'm wondering if there is a simple way to do this for 1D.
so far you cannot use a 1d atmosphere for simulation with a direct
source like the sun because the atmosphere dimension and (radiative
transfer) geometry are coupled in ARTS. Since you have a zenith and an
azimuth dependency for simulation with a direct source, you have to use
a 3d atmosphere in ARTS as simulation of 1d atmospheres have only zenith
dependency in ARTS.
Also, is it possible to just not include surface emission?
No, but you can set the surface temperature to a small value greter than
0 K. This would have a similar effect.
Cheers,
Freddy
