An Example of the Resolution of the Data



The Planetary Fourier Spectrometer (PFS) is a double pendulum Fourier Transform interferometer, with capabilities similar to the Mariner 9 IRIS experiment at thermal infrared wavelengths (250 to 1700 cm^-1 or 5.5 to 45 microns), but it adds a Short Wavelength channel covering the spectral range from 1700 to 8200 cm-1 (1.2 to 5.7 microns). The spectral resolution (1.3 cm^-1) is the same over the entire spectral range.
The specific science measurements pertaining to atmospheres are:

1. Solve the problem of the inversion of the 15 microns CO2 band
2. Obtain the vertical temperature profile without any assumptions about ground pressure and temperature, and retrieve the dust content of the atmosphere.
3. Complete global coverage of Mars in each season, to study seasonal variations in the global circulation
4. Study the mixing ratio of trace gases in the Martian atmosphere


The primary source for The Planetary Fourier Spectrometer (PFS) data is the ESA Planetary Science Archive (PSA)

Through a cooperative agreement between ESA and NASA, the PDS Geosciences Node will host a copy of the PSF data archive on their web site as the data becomes available to them. This, data is housed in the GEO node and at PSA. GEO data may be more accessible but there may be more recent data available at the PSA.
