All‐Altitude Atmospheric Radiation Transport with SAMM2

This paper reviews the capabilities of SAMM2, a high‐fidelity background radiance code. SAMM2 incorporates atmospheric climate and chemistry, line‐of‐sight geometry, spectroscopy and radiation transport into a unified and extensible code. It is capable of accurately predicting atmospheric radiances under both low‐altitude local thermodynamic equilibrium as well as upper‐altitude non‐equilibrium conditions. SAMM2 provides comprehensive coverage in the .4 to 40 micron (250 to 25,000 wavenumber) wavelength region for arbitrary line‐of‐sight inputs. The capabilities of SAMM2 are demonstrated by computing radiance values for typical atmospheric conditions.
