Title : Hotspots of soil organic carbon storage revealed by laboratory hyperspectral imaging

Journal :  Scientific Reports

Comment : 

















 They tested the application of laboratory hyperspectral imaging with a variety of machine learning approaches to predict OC distribution in undisturbed soil cores. Despite a large increase in variance and reduction in OC content with increasing depth, the high resolution of the images enabled statistically powerful analysis in spatial distribution of OC in the soil cores. Laboratory hyperspectral imaging enables powerful, fine-scale investigations of the vertical distribution of soil OC as well as hotspots of OC storage in undisturbed samples, overcoming limitations of traditional soil sampling campaigns.

Year  : 2019 Title  :  Stratification of a local VIS-NIR-SWIR spectral library by homogeneity criteria yields more accurate soil organic carbon predictions Journal  :  Geoderma Comment   :    The aim of this research was to  i) characterize and identify differences among spectra obtained for subtropical soils samples, ii)  evaluate different pre-processing techniques and multivariate methods to propose SOC prediction models from  the spectral data and iii) evaluate the performance of SOC prediction models calibrated from the stratification of  a local library.  Spectral reflectance measurements were performed in the  laboratory with a spectroradiometer in the range of 350–2500 nm. Six pre-processing techniques were applied to  the spectra (including derivatives, normalization and non-linear transformations) and four multivariate calibration  methods, namely, partial least

Burrows & Alfonso Saiz-Lopez Year  : 2014 Title  :  Evolution of NO2 levels in Spain from 1996 to 2012 Journal  : Scientific reports Comment   : In this work, they report on the NO2 geographical distribution and concentration trends over Spain using combined multiple satellite datasets and ground-based observations from five metropolitan areas in the country: Madrid, Barcelona, Valencia, Sevilla and Bilbao. NOx emissions in a country or region are directly related to its industrial and economic development. The results in these five cities show a smooth decrease in the NO2 concentrations of, 2% per year in the period 1996–2008, due to the implementation of emissions control environmental legislation, and a more abrupt descend of,7% per year from 2008 to 2012 as a consequence of the economic recession.
