PLANETARY FOURIER SPECTROMETER

INFRARED REMOTE SENSING OF THE ATMOSPHERE AND SURFACE

Main scientific objectives of the atmosphere studies:

  • monitoring of 3D temperature and pressure fields;
  • global mapping of winds;
  • variations of H2O and CO in space and time;
  • aerosols: optical depth, phase function, size distribution and chemical composition.

    Main scientific objectives of the surface studies:
  • temperature and thermophysical properties of soils;
  • mineralogical composition of the surface;
  • surface condensates;
  • altimetry.

    Instrument is a two-channel Fourier-spectrometer

    Main performance characteristics:
