Description: Line-By-Line Radiative Transfer Model
The Line-by-Line Radiative Transfer Model (LBLRTM) is a product of Atmospheric and Environmental Research, Incorporated (AER). The LBLRTM is based on the FASCODE line-by-line model, wherein the radiative transfer aspect of the code has been substantially rewritten to support operation on vector processing platforms. A radiance algorithm has been used to treat the vertically inhomogeneous atmospheres resulting in substantially improved accuracy, and the model is directly applicable to longwave cooling rate calculations.
