Title Light pollution modeling and detection in a heterogeneous environment Type Journal Article

Abstract Few attempts have been made to measure aerosol optical depth (AOD) behaviour

during the night. One such method uses spectrally calibrated stars as reference targets

but the available number of stars is limited. This is especially true for urban sites where

artificial lighting hide most of these stars. In our research we attempt to provide an

alternate method one which exploits the artificial sky glow generated by light pollution.

To achieve that goal, we designed a new methodology which links a 3D light

pollution model with in situ light pollution spectral measurements obtained with our

detector called Spectrometer for aerosol night detection (SAND). The basic idea was to

adjust an AOD value into the model in order to fit the measured artificial sky brightness.

This method requires an accurate model that includes spatial heterogeneity in lighting

angular geometry, in lighting spectral dependence, in ground spectral reflectance and

in topography along with a detailed definition of the vertical atmospheric profile. This

model, named ILLUMINA, computes 1st and 2nd order molecular and aerosol scattering

as well as aerosol absorption. A correction for sub grid obstacles is also included.

These model features represent major improvements to previous light pollution models.

Therefore, new possibilities for light pollution studies will arise, many of which are of

particular interest to the astronomical community. In this paper we will present model

and detector features and some of the first results derived from ILLUMINA model. We

will also present our web based spatio-temporal Sky spectral luminance measurements

database project.

Title Introducing the Bortle Dark-Sky Scale. Type Journal Article
Year 2001 Publication Sky & Telescope Abbreviated Journal Sky Telesc
Volume (up) Issue 60 Pages 126-129
Keywords Vision; skyglow; visibility; sky brightness
Abstract How dark is your sky? The relationship between light pollution and astronomy is a concern amateurs and professional astronomers alike. Are your skies dark enough? A precise answer to this question is useful for comparing observing sites and, more important, for determining whether a site is dark enough to let you push your eyes, telescope, or camera to their theoretical limits. Likewise, you need accurate criteria for judging sky conditions when documenting unusual or borderline observations, such as an extremely long comet tail, a faint aurora, or subtle features in galaxies.

Title 'When the lights stay on' – A novel approach to assessing human impact on the environment. Earth. Type Journal Article
Year 2008 Publication Earthzine Abbreviated Journal
Volume (up) Issue Pages
Keywords Ecology
Abstract A consequence of the explosive expansion of human civilization has been the global loss of biodiversity and changes to life-sustaining geophysical processes of Earth. The footprint of human occupation is uniquely visible from space in the form of artificial night lighting – ranging from the burning of the rainforest to massive offshore fisheries to omnipresent lights of cities, towns, and villages. This article describes a novel approach to assessing global human impact using satellite observed nighttime lights. The results provide reef managers and governments a first-pass screening tool for reef conservation projects. Sites requiring restoration and precautionary actions can be identified and assessed further in more focused investigations. We hope to create a mental picture for others to see and encourage participation in maintaining and restoring the natural world.
