Dr R. Todd Clancy is a Senior Research Scientist at SSI, which he joined as its first full-time research scientist in late 1994. At that time Dr. Clancy participated in the design of the first MarsQuest exhibit, based upon his extensive involvement in Mars climate research via ground-based, Hubble Space Telescope (HST), and Mars Global Surveyor (MGS) observational programs. Currently, Dr. Clancy is a member of the Thermal Emission Spectrometer (TES) onboard the operational MGS orbiter, a continuing HST monitoring program for Mars, and two experiments (MARCI, a UV-visible camera and CRISM, a visible-near infrared spectrometer) in development for the 2005 Mars Reconnaissance Orbiter. Dr. Clancy is a specialist in remote sounding and radiative transfer retrievals of Mars, Venus and terrestrial atmospheric properties, ranging from dust and cloud aerosols to trace chemical species (such as ozone) to dynamical state variables (such as temperature and winds). Based upon previous ground and space-based observations of Mars, Dr. Clancy has determined fundamental annual forcings of Mars climate and atmospheric chemistry due to the large eccentricity of the Mars orbit.
