Abstract
The GHIS FTIR spectrometer is designed to be a plug-in replacement for the low-resolution filter wheel spectrometer employed in current GOES sounders. State-of-the-art retrieval algorithms will be able to produce atmospheric temperature and humidity profiles with improved vertical resolution and smaller uncertainties as a results of the instrument's higher spectral resolution. MIT Lincoln Laboratory has designed, assembled, and performed visible- wavelength tests of a GHIS brassboard spectrometer. Details of the assembly procedure will be presented, showing how the optical components were individually tested, then pre- aligned and integrated into the instrument at room temperature for eventual operation at a nominal 220K.
