The European Space Agency
Mars Express: PFS

The Martian atmosphere consists mainly of carbon dioxide and nitrogen with a very small proportion of water vapour and ozone. The PFS (Planetary Fourier Spectrometer) will measure the global atmospheric distribution of water vapour and other minor constituents with greater accuracy than previous missions. The PFS Principal Investigator is Dr. Marco Giuranna, Istituto di Astrofisica e Planetologia Spaziali, Rome, Italy.

The primary source for PFS data is the ESA Planetary Science Archive.

Through a cooperative agreement between ESA and NASA, the PDS Geosciences Node is hosting a copy of the PFS data archive.
