Ground calibration algorithms for a Geosynchronous Imaging FTS (GIFTS) are being developed at the University of Wisconsin-Madison Space Science and Engineering Center. This development is being conducted in support of NOAA's GOES-R Risk Reduction program with a focus on the hyperspectral sounder that is anticipated to be a part of the GOES-R Hyperspectral Environmental Suite (HES). The near term objective is to develop calibration algorithms that can be evaluated using thermal vacuum test data from NASA's Geosynchronous Imaging Fourier Transform Spectrometer (GIFTS). The GIFTS is designed to produce 128x128 interferograms in two spectral bands every 11 seconds using a Michelson interferometer and two detector focal plane arrays. In preparation for the thermal vacuum test data, simulated data has been used in the GIFTS Information Processing System (GIPS) to demonstrate tradeoffs in alternative algorithms for the radiometric calibration of the GIFTS. The GIPS provides a realistic prototyping environment for assessing the tradeoffs between implementation efficiency and product accuracy.
