Geosynchronous Imaging FTS (GIFTS)
Combine Advanced Measurement Technologies On a
Geosynchronous Satellite to Obtain 4-D
Observations 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)
