Silicate mineralogy at the surface of Mercury
© 2017 Macmillan Publishers Limited, part of Springer Nature. All rights reserved. NASA's MESSENGER spacecraft has revealed geochemical diversity across Mercury's volcanic crust. Near-infrared to ultraviolet spectra and images have provided evidence for the Fe 2+ -poor nature of silicate minerals, magnesium sulfide minerals in hollows and a darkeni...
A sub km resolution global database of surface reflectance and emissivity based on 10-years of MODIS data
The MODIS instruments have been flying onboard the Terra and Aqua platforms and have acquired Earth observation data since early 2000 and mid 2002, respectively. After atmospheric correction, the collected data allows the monitoring of the land cover dynamics. Here, we describe a data processing scheme to generate Earth reflectance and emissivity t...
Prediction of specialty coffee cup quality based on near infrared spectra of green coffee beans.
Published in Talanta
The growing global demand for specialty coffee increases the need for improved coffee quality assessment methods. Green bean coffee quality analysis is usually carried out by physical (e.g. black beans, immature beans) and cup quality (e.g. acidity, flavour) evaluation. However, these evaluation methods are subjective, costly, time consuming, requi...
Land surface remote sensing in agriculture and forest
Spectral unmixing refers to the process by which the spectrum measured over a mixed target is decomposed into a collection of pure component spectra called endmembers and their fractional abundances. Mixed targets are frequently encountered in remote sensing and spectral unmixing techniques have been mostly developed for visible and near-infrared (...
Near infrared spectroscopy of soils
...
Near infrared (NIR) and mid-infrared (mid-IR) reflectance spectroscopy are time- and cost-effective tools for characterising soil organic carbon (SOC). Here they were used for quantifying (i) carbon (C) dioxide (CO2) emission from soil samples crushed to 2 mm and 0.2 mm, at 18°C and 28°C; (ii) physical C protection, calculated as the difference bet...
Near infrared spectroscopy of soils
In soil science, structural features of soils are an important attribute; soils can be characterised by proportional size distribution of aggregates and the pore space between and within those aggregates. The objective of this study was to evaluate the relationship between the visible and near infrared (Vis–NIR) spectra and microaggregates from a c...
