    SPICAM is a Mars Express instrument designed to measure the composition of the Martian atmosphere. It is an imaging spectrometer for ultraviolet and infrared radiation that was designed to acquire atmospheric data utilizing limb grazing and stellar occultation techniques. These data include vertical profiles of carbon dioxide, temperature, ozone, aerosols and clouds. It measures ozone using a technique similar to that used on the Mariner 9 spacecraft.

    The SPICAM instrument has two channels, one in the ultraviolet wavelength range (118-320 nanometers) (SUV) and another in the near infrared wavelength range (1.1-1.7 micrometers) (SIR) . The instrument has a spectral resolution of 0.8 nm/pix at 1.5μ and is composed of an entrance lens, an AOTF and two single pixels detectors (for each polarization). As the AOTF acts as a filter, the IR & UV spectrum is obtained by electrically scanning the AOTF frequency.

    The primary source for SPICAM 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 SPICAM data archive on their web site when it 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.
