Dear Haung,
As Jana, I get puzzled about "cloudy sky". There is no support for doing
retrievals with scattering. Do you mean retrievals with purely absorbing
liquid clouds?
Uh, it could be that you are the first one using the LoadTable option!
To test this, just try to save your absorption table to a file as
(assuming it variable name is A):
xmlStore ('test.xml', A, 'GasAbsLookup');
An OK A should look like:
A =
species: {{1x1 cell} {1x1 cell} {1x1 cell}}
nonlinear_species: {}
f_grid: [2x1 double]
p_grid: [202x1 double]
vmrs_ref: [3x202 double]
t_ref: [202x1 double]
t_pert: []
nls_pert: []
xsec: [4-D double]
What version of qpack/arts are you using?
Kind regards,
Patrick
