FUTBOLIN (FUll Transfer By Optimized LINe-by-line methods) is a radiative transfer model for the calculation of line-by-line atmospheric emission/transmission spectra in planetary atmospheres.
It allows generating high-resolution synthetic spectra in the 0.3-1000 micrometre spectral range.
[citation needed] The code can handle spherical or plane-parallel atmospheres.
It also takes into account the Non Local Thermodynamic Equilibrium (NLTE) effects on the rotational, electronic and vibrational populations of the atmospheric species and allows to specify any combinations of clouds, coverage and spectral albedo.
The code can calculate reflection, transmission, absorption, infrared cooling rate, and flux spectra.
