Replacement of the sounder filter wheel in one of the clones of the GOES I-M satellite series with a Fourier transform infrared (FTIR) interferometer would improve retrieval performance and could be a pathfinder for technology employed in the next generation GOES series. Based on examination of an earlier proposal, NOAA decided to pursue the feasibility of such a FTIR replacement. The FTIR interferometer is to be as nearly a 'plug-in' replacement for the sounder filter wheel as possible. THis imposes some interesting and challenging optical, mechanical, and electronic constraints on the design and fabrication of the interferometer. This overview describes a brassboard design for a replacement FTIR interferometer and provides the background and the status of GHIS brassboard work-in- progress at MIT Lincoln Laboratory.
