Multispectral Orbital Retrieval using Sequential Estimation

MORSE v4 is a Fortran90 program to retrieve profiles of atmospheric temperature and composition from satellite infrared spectra (primarily MIPAS and IASI) in limb or nadir-viewing mode.

It requires (up to) an orbit of satellite data (MIPAS L1B or IASI L1C format) to be converted via an IDL L1C pre-processor into a suitable input format, and can then either be run with standard HITRAN spectroscopic input or pre-defined Look-Up Tables. The former is suitable for small-scale, investigative work while the latter is for more systematic large-scale processing.
