On the Posch ratio for irradiance in coastal waters and the high seas
Xabier Pérez-Couto, Fabio Falchi, Salvador Bará
The horizontal irradiance at the sea surface is an informative light pollution indicator to study Artificial Light at Night (ALAN) effects on marine biodiversity (e.g.: zooplankton…
Light pollution is skyrocketing
Fabio Falchi, Salvador Bará
Artificial light at night is a pollutant that is rising fast, as demonstrated by Kyba et al. (1) work by analyzing ten of thousands observations by citizen scientists in the last 1…
Light pollution and the concentration of anthropogenic photons in the terrestrial atmosphere
Salvador Bará, Carmen Bao-Varela, Fabio Falchi
Light pollution can be rigorously described in terms of the volume concentration of anthropogenic photons (light quanta) in the terrestrial atmosphere. This formulation, consistent…
Towards a global map of the artificial all-sky brightness
Miroslav Kocifaj, Salvador Bará, Fabio Falchi
Modeling the hemispherical night sky brightness of anthropogenic origin is a demanding computational challenge, due to the intensive calculations required to produce all-sky maps w…
Estimating linear radiance indicators from the zenith night sky brightness: on the Posch ratio for natural and light polluted skies
Salvador Bará, Xabier Pérez-Couto, Fabio Falchi +2
Estimating the horizontal irradiance from measurements of the zenith night sky radiance is a useful operation for basic and applied studies in observatory site assessment, atmosphe…
Can we illuminate our cities and (still) see the stars?
Salvador Bará, Fabio Falchi, Raul C. Lima +1
Could we enjoy starry skies in our cities again? Arguably yes. The actual number of visible stars will depend, among other factors, on the spatial density of the overall city light…
