CÉGEP de Sherbrooke, Canada Université de Sherbrooke, Canada TitleAssessing the contribution from different parts of Canary islands to the hemispheric spectral sky luminance levels over European Northern Observatories. SummaryWe suggest to use a third generation sky luminance model which account for heterogeneous distribution of light fixtures, their photometry, the ground reflectance and topography along with hyperspectral sky luminance measurements to infer contribution of different zones of Canary islands to astronomical observation sites sky luminances. This sensitive study will allow the identification and evaluation of critical island zones. The project aim to identify and characterize zones at which any lighting level increase or decrease may have a larger impact on light pollution at both European Northern Observatory sites, and then help to control and/or reduce their light pollution levels.
