GIFTS (Geostationary Imaging Fourier Transform Spectrometer)
An experimental remote-sensing satellite that will use an advanced instrument called an Imaging Fourier Transform Spectrometer to observe atmospheric temperature, water vapor content and distribution, and the concentration of certain other atmospheric gases present at a given altitude over time. By noting changes in temperature, water vapor, and gases that modulate energy in different regions of the electromagnetic spectrum, scientists will get an accurate picture of what is happening in the atmosphere and what weather is likely to develop. Part of NASA's New Millennium Program, GIFTS is mainly intended to space-validate cutting-edge technologies for future use.
