Light pollution in Spain. An european perspective

TL;DR

This paper analyzes light pollution in Spain, revealing that despite appearing less polluted on maps, Spain is among the most contaminated European countries when considering population density and comparing with other nations.

Contribution

It provides a comparative analysis of light pollution in Spain relative to other European countries, highlighting the discrepancy caused by population density effects.

Findings

Spain is highly contaminated with light pollution when adjusted for population density.

Light pollution maps may underestimate Spain's pollution levels due to population distribution.

Spain ranks among the most polluted European countries in terms of light pollution.

Abstract

Spain appears in light pollution maps as a country less polluted than their neighbours in the European Union. This seems to be an illusion due to its low population density. The data indicate that Spain is one of the most contaminated countries. To reach these conclusions we compare the Spanish case to those of other European countries.
