The Tropospheric Emission Spectrometer (TES) is an imaging infrared Fourier-transform spectrometer scheduled to be launched into polar Sun-synchronous orbit aboard the Earth Observing System's Aura satellite in June 2003. The primary objective of the TES is to make global three-dimensional measurements of tropospheric ozone and of the physical-chemical factors that control its formation, destru...

Lunar meteorite chip samples recovered by the National Institute of Polar Research (NIPR) have been studied by a UVevisibleenear-infrared spectrometer, targeting small areas of about 3 2 mm in size. Rock types and approximate mineral compositions of studied meteorites have been identified or obtained through this spectral survey with no sample preparation required. A linear deconvolution method...

We present laboratory studies of the radiolysis of pure (97%) solid H2O2 films by 50 keV H+ at 17 K. Using UV-visible and infrared reflectance spectroscopies, a quartz-crystal microbalance, and a mass spectrometer, we measured the absolute concentrations of the H2O, O2, H2O2, and O3 products as a function of irradiation fluence. Ozone was identified by both UV and infrared spectroscopies and O2...

We have observed a bright flare of Sgr A* in the near infrared with the adaptive optics assisted integral field spectrometer SINFONI. Within the uncertainties, the observed spectrum is featureless and can be described by a power law. Our data suggest that the spectral index is correlated with the instantaneous flux and that both quantities experience significant changes within less than one hou...

The antarctic plateau has the potential for being the best site on Earth for conducting astronomical observations from the near-infrared to the sub-millimeter. Particular gains are expected in the 1 to 5 micron region, where the high altitude, low water vapour content, and low thermal emission from the atmosphere combine to create observing conditions unequalled elsewhere on the surface of the ...

Researchers seek to identify dry lake bed deposits on Mars, if present. The Global Surveyor TES and Mars Odyssey THEMIS are primary tools in this search. However, there are no published thermal infrared spectrometer (hyperspectral) airborne studies of a dry lake bed. Here we present the first such study and the impacts on TES/THEMIS interpretations. This research addresses a looming gap in the ...

Fourier Transform Infrared (FTIR) microscopy is a well-established method for the analysis of samples that are too small or complex to be measured in a standard infrared spectrometer. With FTIR microscopy, it is possible to readily visualize the sample and determine the area(s) of interest. IR spectra are then easily collected with excellent spatial resolution, thereby revealing the chemical co...

Introduction: Measurements of the martian atmosphere have experienced rapid growth during the past decade. As on Earth, remote sensing from orbit offers the advantage of nearly continuous, global coverage and a host of instruments have been employed for this purpose, including cameras [the Mars Orbiter Camera (MOC) and the Mars Color Imager (MARCI)] and infrared sounders [the Thermal Emission S...
