MonoRTM is a radiative transfer model, designed to process one or a number of monochromatic wavenumber values. It is particularly useful in the microwave spectral region. It is also applicable for atmospheric laser propogation studies.
MonoRTM attributes include:
utilizes the same physics and continuum model as the Line-by-line Radiative Transfer Model, LBLRTM.
suitable for the calculation of radiances associated with absorption by molecules and cloud liquid water in the atmosphere
applicable to uplooking/downlooking configuations
spectral validity depends only on the spectral region covered by the spectral lines provided in the line parameter database file
the Monochromatic Optical Depth Model (MODM) module is the core component of MonoRTM, dedicated to the calculation of the molecular optical depths
uses the CKD continuum to include contributions from the far wings of the lines [Clough et al., 1989; CKD]
includes line coupling effects, which are important for oxygen lines in the microwave region [Hoke et al., 1989]
uses the Humlicek Voigt Line Shape [J. Humlicek, 1982]
cloud liquid water absorption is calculated using a model developed by the Liebe, Hufford and Manabe [1991]
