MIRART, a line-by-line code for infrared atmospheric radiation computations incl. derivatives

A suite of programs MIRART (Modular InfraRed Atmospheric Radiative Transfer) for high resolution infrared atmospheric radiative transfer calculations has been developed with emphasis on efficient and reliable numerical algorithms and a modular approach appropriate for simulation and/or retrieval in a variety of applications. The code has been carefully tested in the framework of two extensive intercomparisons. Molecular weighting functions are implemented by means of automatic differentiation.
