Received 2 March 2008; revised 29 July 2008; accepted 18 September 2008; published 31 December 2008. [1] We evaluated the spatial variation of Venusian surface emissivity at 1.18 mm wavelength and that of near-surface atmospheric temperature using multispectral images obtained by the Near-Infrared Mapping Spectrometer (NIMS) on board the Galileo spacecraft. The Galileo NIMS observed the nightside thermal emission from the surface and the deep atmosphere of Venus, which is attenuated by…

Venus surface thermal emission at 1 μm in VIRTIS imaging observations: Evidence for variation of crust and mantle differentiation conditions
[1] The Venus Express spacecraft images the nightside thermal emissions using the Visible and Infrared Thermal Imaging Spectrometer (VIRTIS). At 1.02, 1.10, and 1.18 μm, thermal emission from the
Multi-spectrum retrieval of maps of Venus' surface emissivity in the infrared
The main goal of this cumulative thesis is the derivation of surface emissivity data in the infrared from radiance measurements of Venus. Since these data are diagnostic of the chemical composition
Deriving iron contents from past and future Venus surface spectra with new high-temperature laboratory emissivity data
The new laboratory data show that different rock types can be distinguished using only a small set of spectral bands, and future orbital spectral observations can provide a much-needed global composition map.
The Venus Emissivity Mapper (VEM): obtaining global mineralogy of Venus from orbit
The Venus Emissivity Mapper is the first flight instrument designed with a focus on mapping the surface of Venus using atmospheric windows around 1 μm. After several years of development VEM has a
Venus Surface Composition Constrained by Observation and Experiment
New observations from the Venus Express spacecraft as well as theoretical and experimental investigation of Venus analogue materials have advanced our understanding of the petrology of Venus melts


On observing the compositional variability of the surface of Venus using nightside near‐infrared thermal radiation
[1] There are several windows in the near-infrared wavelength range (∼1 μm), in which thermal radiation emitted from the planetary surface penetrates through the thick Venus atmosphere and clouds. In
Galileo/NIMS near-infrared thermal imagery of the surface of Venus
Numerous highland and lowland features on the surface of Venus are observed in multispectral imagery acquired at approximately 50 km spatial resolution by the Near-Infrared Mapping Spectrometer
Ground‐based near‐infrared observations of the Venus nightside: The thermal structure and water abundance near the surface
We used ground-based near-infrared (NIR) observations of thermal emission from the Venus nightside to determine the temperature structure and water vapor distribution between the surface and the 6-km
Venus surface radiothermal emission as observed by Magellan
The Magellan radiometer experiment has observed the 12.6-cm-wavelength radio emissivity of more than 91% of the Venus surface during the first 8 months of its operation. The global mean value of
Near-Infrared Mapping Spectrometer experiment on Galileo
The Galileo Near-Infrared Mapping Spectrometer (NIMS) is a combination of imaging and spectroscopic methods. Simultaneous use of these two methods yields a powerful combination, far greater than when
Near-infrared light from Venus' nightside - A spectroscopic analysis
Abstract We have simulated near-infrared spectra of the emission from Venus' nightside with a radiative transfer program that allows for emission, absorption, and scattering by atmospheric gases and
Mineral equilibria and the high radar reflectivity of Venus mountaintops
We studied the relationship between altitude and microwave emissivity (the complement of power reflectivity) in 10 highland regions of Venus, using the Magellan data set. Above a critical altitude
Galileo Infrared Imaging Spectroscopy Measurements at Venus
During the 1990 Galileo Venus flyby, the Near Infaied Mapping Spectrometer investigated the night-side atmosphere of Venus in the spectral range 0.7 to 5.2 micrometers to derive lower atmosphere abundances of water vapor and other species.
The Nature of the Near-Infrared Features on the Venus Night Side
Near-infrared images of the Venus night side show bright contrast features that move from east to west, in the direction of the cloud-top atmospheric superrotation, which indicates that there are partial clearings in this cloud deck.
