The Geosynchronous Imaging Fourier Transform Spectrometer (GIFTS) represents a revolutionary step in satellite based remote sensing of atmospheric parameters. Using a combination of a Fourier Transform Spectrometer and Large Area Focal Plane Arrays, GIFTS will measure the Earth emitted radiance at the top of atmosphere from geosynchronous orbit with an unprecedented combination of spectral, temporal, and spatial resolution and coverage. In its Regional Sounding and Chemistry mode, GIFTS will measure the infrared spectrum in two bands (14.6 to 8.8 µm, 6.0 to 4.4 µm) at a spectral resolution of ~0.6 1/cm for a 128x128 set of ~4 km footprints (a ~512 x 512 km area) every eleven seconds. In the project's formulation phase, these data "cubes" have been simulated in order to support algorithm development efforts and instrument trade studies. In particular, the simulated data has been used to develop and test algorithms for on-board lossy data compression experiments. This poster presents the simulation methodology and gives examples of the simulated GIFTS data.
