to Obtain to Obtain 4-D Observations4-D Observations of the Atmosphere of the Atmosphere

• Horizontal: Large detector arrays give near instantaneous wide 2-D geographical coverage

• Vertical: Michelson interferometer (FTS) gives high spectral resolution that yields high vertical resolution

• Temporal: Geosynchronous orbit allows high time resolution(i.e., motion observations)

What does NOAA GOES-RRR learn from GIFTS?

Thermal Vacuum Testing

• Demonstrate optical design using high precision internal calibration blackbodies for enhanced accuracy from geo orbit.

• Instrument Line Shape will be characterized for an Imaging FTS.

• Experience with FPA cross-talk, noise correlation, linearity.

• Experience gained in simulation of imaging GEO sounder.

• Development of metadata ontology for hyperspectral observations.

• Experience gained in the development and use of high performance computing software as a demonstration of future HES sounder ground data processing (OSD).
