We describe a new instrument designed to observe the temperature, pressure, density, and composition of the Martian atmosphere with unprecedented accuracy and precision. The MATADOR instrument is a 12-channel limb scanning infrared radiometer and is an improved design based upon the highly successful Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument that has now achieved five years of operation in Earth orbit on the NASA TIMED mission. The twelve discrete MATADOR channels span a wavelength range from 1.27 um to 22.2 um. The focal plane is cooled by a small mechanical cryocooler. The mass of the instrument is approximately one-half that of the SABER-TIMED instrument. MATADOR is more than twice as sensitive as the SABER instrument. In addition to temperature and density, MATADOR will also provide vertical profiles of dust opacity (at several wavelengths), water vapor, water ice, carbon monoxide, carbon dioxide, and ozone. The instrument design and anticipated performance are reviewed, along with detailed simulations of the retrievals of Martian atmospheric composition.
