TL;DR: In this article, the authors combine the updated Gridded Population of the World (GPW2) population distribution estimate for 1990 and lighted settlement imagery with a global digital elevation model (DEM) and a high resolution vector coastline.

TL;DR: In this paper, the tradeoff between blooming and attenuation of smaller lights was investigated in stable night lights datasets, and a Gaussian detection probability model was used to find a linear relationship between atmospheric scattering combined with a random geolocation error.

TL;DR: In this article, the applicability of linear spectral mixture models to the estimation of urban vegetation abundance using Landsat Thematic Mapper (TM) data was examined, and a three-component linear mixing model provided stable, consistent estimates of vegetation fraction for both constrained and unconstrained inversions of three different endmember ensembl...

TL;DR: The proportion of wells that exceed the Bangladesh standard for drinking water of 50 μg/L arsenic increases with depth from 25% between 8 and 10 m to 75% between 15 and 30 m, then declines gradually to less than 10% at 90 m as mentioned in this paper.

TL;DR: Environmental exposures after the WTC disaster were associated with significant adverse effects on health, and the high alkalinity of WTC dust produced bronchial hyperreactivity, persistent cough, and increased risk of asthma.
