Vertical Distributions of Water Vapor and Aerosol in the Martian Atmosphere by Spicam-ir Spectrometer on Mars-express

Characterization of the stray light in a space borne atmospheric AOTF spectrometer.

Acousto-optic tunable filter (AOTF) spectrometers are being criticized for spectral leakage, distant side lobes of their spectral response function (SRF), or the stray light. SPICAM-IR is the AOTF spectrometer in the range of 1000-1700 nm with a resolving power of 1800-2200 operating on the Mars Express interplanetary probe. It is primarily dedicated to measurements of water vapor in the Martia...

Adsorption of HO x on aerosol surfaces Implications for the atmosphere of Mars

The potential impact of heterogeneous chemistry on the abundance and distribution of HOx in the atmosphere of Mars has been assessed by combining observational data of dust and ice aerosol distributions with an updated photochemical model. Critical parameters include the altitude distributions of aerosols, and the surface loss coefficients (T) of riO2 on dust and ice in the lower atmosphere, an...

Interannual Variability of the Mars Thermosphere: New Simulations and Comparisons with Recent Mars Datasets

Detailed studies exist that explore the global, seasonal, and interannual variations of the Martian lower atmosphere (below 90 km) [e.g. Liu et al., 2003]. Key findings indicate that observed temperatures are quite repeatable from one Mars aphelion season to the next. Conversely, perihelion temperatures can change radically on an interannual basis, depending on the timing and intensity of dust ...
