Line-by-line spectroscopic simulations on graphics processing units

Abstract We report here on software that performs line-by-line spectroscopic simulations on gases. Elaborate models (such as narrow band and correlated-K) are accurate and efficient for bands where various components are not simultaneously and significantly active. Line-by-line is probably the most accurate model in the infrared for blends of gases that contain high proportions of H_2 O and CO_2as this was the case for our prototype simulation. Our implementation on graphics processing units sustain...
