Optical and radiometric models of the NOMAD instrument part II: the infrared channels - SO and LNO
(Optics Express, 2016-02-16)
NOMAD is a suite of three spectrometers that will be launched in 2016 as part of the joint ESA-Roscosmos ExoMars Trace Gas Orbiter mission. The instrument contains three channels that cover the IR and UV spectral ranges ...
Nitrogen and phosphorus loads to temperate seepage lakes associated with allochthonous dissolved organic carbon loads
(American Geophysical Union, 2018-06-16)
Terrestrial loads of dissolved organic matter (DOM) have increased in recent years in many north temperate lakes. While much of the focus on the “browning” phenomena has been on its consequences for carbon cycling, much ...
Temporal observations of bright soil exposures at Gusev crater, Mars
(Journal of Geophysical Research, 2011-01-27)
The Mars Exploration Rover Spirit has discovered bright soil deposits in its wheel tracks that previously have been confirmed to contain ferric sulfates and/or opaline silica. Repeated Pancam multispectral observations ...
Summer storms trigger soil N₂O efflux episodes in forested catchments
(American Geophysical Union, 2016-01-14)
Climate change and climate-driven feedbacks on catchment hydrology and biogeochemistry have the potential to alter the aquatic versus atmospheric fate of nitrogen (N) in forests. This study investigated the hypothesis that ...
Imaging spectroscopy of geological samples and outcrops: Novel insights from microns to meters
(GSA Today, 2015-12-01)
Imaging spectroscopy is a powerful, non-destructive mineralogic tool that provides insights into a variety of geological processes. This remote measurement technique has been used for decades from orbital or aerial platforms ...
Physical characterization of ~2 m diameter near-Earth asteroid 2015 TC25: A possible boulder from E-type asteroid (44) Nysa
(The Astronomical Journal, 2016-11-11)
Small near-Earth asteroids (NEAs) (<20 m) are interesting, because they are progenitors for meteorites in our terrestrial collection. The physical characteristics of these small NEAs are crucial to our understanding of the ...
Automated LULC Map Production using Deep Neural Networks
(Taylor & Francis, 2019-01-17)
This article presents an approach to automating the creation of land-use/land-cover classification (LULC) maps from satellite images using deep neural networks that were developed to perform semantic segmentation of natural ...
Detection of rotational spectral variation on the M-type asteroid (16) Psyche
(The Astronomical Journal, 2016-12-28)
The asteroid (16) Psyche is of scientific interest because it contains ∼1% of the total mass of the asteroid belt and is thought to be the remnant metallic core of a protoplanet. Radar observations have indicated the ...
Submicroscopic metallic iron in lunar soils estimated from the in situ spectra of the Chang’E-3 mission
(Geophysical Research Letters, 2017-04-22)
Submicroscopic metallic iron (SMFe) created by space weathering has strong effects on the optical properties of the lunar surface. Spectra measured in situ by the visible-near-infrared spectrometer (VNIS) on board the ...
