TLDR
Large portions of the thermal emission spectra are significantly affected by dust with a silicon oxide content approximately corresponding to that of an intermediate igneous rock, thus implying that Mars has undergone substantial geochemical differentiation.Abstract:
The Mariner 9 infrared spectroscopy experiment has provided goodquality spectra of many areas of Mars, predominantly in the southern hemisphere. Large portions of the thermal emission spectra are significantly affected by dust with a silicon oxide content approximately corresponding to that of an intermediate igneous rock, thus implying that Mars has undergone substantial geochemical differentiation. Derived temperature profiles indicate a warm daytime upper atmosphere with a strong warming over the south polar cap. Atmospheric water vapor is clearly observed over the south polar area and less strongly over other regions.read more

TL;DR: The Thermal Emission Imaging System (THEMIS) on 2001 Mars Odyssey will investigate the surface mineralogy and physical properties of Mars using multi-spectral thermal-infrared images in nine wavelengths centered from 6.8 to 14.9 μm, and visible/near-in infrared images in five bands centered from 0.42 to 0.86 μm.

TL;DR: The behavior of Mars as observed by the Viking infrared thermal mapper (IRTM) is considered in this article, where the IRTM is a 28-channel, 4-telescope radiometer that operated in six spectral bands.

Physical properties of the particles composing the Martian dust storm of 1971–1972
TL;DR: In this article, the infrared interferometric spectrometer (IRIS) data collected by the Mariner 9 spacecraft during the global Martian dust storm of 1971-1972 is analyzed to study the particle sizes in detail, estimate the dust particle size distribution, and determine the dust optical depth.

Thermal structure of the Martian atmosphere during the dissipation of the dust storm of 1971
TL;DR: In this paper, the authors examined the secular variation of the thermal structure of the Martian atmosphere during the dissipation phase of the 1971 dust storm using temperatures obtained by the infrared spectroscopy investigation on Mariner 9.

TL;DR: In this article, spectral features due to the atmospheric dust storm indicate that large diurnal variations in atmospheric temperature existed up to at least 30 km; winds inferred from the temperature fields show a strong tidal component and significant ageostrophic behavior.

Behavior of carbon dioxide and other volatiles on Mars.
TL;DR: A rather simple thermal model of the Martian surface, in combination with current observations of the atmospheric composition, points strongly toward the conclusion that the polar caps of Mars consist almost entirely of frozen CO2.

A study of the thermal and dynamical structure of the martian lower atmosphere
Peter Gierasch,Richard Goody +1 more
TL;DR: The scaling of the equations of motion in the lowest one or two scale heights of the martian atmosphere is discussed in this article, where it is shown that seasonal and diurnal temperature changes can probably be computed with satisfactory precision without taking account of the advection and convection of heat by planetary-scale winds.

Mariner 1969 infrared radiometer results - Temperatures and thermal properties of the Martian surface
TL;DR: In this paper, the reduced data of the Mariner 6 and 7 Infrared Radiometer Experiments are presented, along with a discussion of the reduction and calibration procedures, and evidence is presented showing that the surface of Mars is strongly nonhomogeneous in its thermal properties, on scales ranging from those of the classical light and dark areas to the limit of resolution of the radiometers.
