High-resolution atmospheric observations by the Mars Odyssey Thermal Emission Imaging System

Seasonally active frost‐dust avalanches on a north polar scarp of Mars captured by HiRISE

“…The second type comprises individual and sets of jets of particulate material up to ∼30 km long streaming along the NPLD surfaces to the south of the discovery scarp. These features are more similar to the sheets and jets of material emanating from SPLD surfaces on a yet larger scale observed by THEMIS [ Inada et al , 2007]. These jets occur in one of the images containing gusts, suggesting the latter may be a smaller manifestation of the former, possibly due to strong winds present over several days.…”

Mars’ water vapor mapping by the SPICAM IR spectrometer: Five martian years of observations

“…THEMIS has been conducting mapping operations from Mars orbit since February 2002 . Along with surface mapping, THEMIS routinely monitors dust and water ice aerosol IR opacities (Smith et al, 2003) with its multi-spectral infrared detector (THEMIS-IR) and images clouds and dust (Inada et al, 2007) with its visibleband subsystem (THEMIS-VIS). The IR mapping is done using ten spectral filters covering the thermal infrared range between 6.5 and 15 lm.…”

Concatenation of HRSC colour and OMEGA data for the determination and 3D-parameterization of high-altitude CO2 clouds in the Martian atmosphere

“…Mesospheric cloud altitude and direct cloud velocity measurements have been reported for equatorial clouds by McConnochie et al (2005, submitted for publication) and Inada et al (2007) based on observations with the Mars Odyssey Thermal Emission Imaging System (THEMIS). The THEMIS-VIS colour channels apply a push-frame imaging technique (McConnochie et al, 2006) which results in a rather small time-delay and parallax offset between the colour channel images.…”
