Spectral Relative Attenuation of Solar Radiation through a Skylight Focused on Preventive Conservation: Museo De L'almoina in Valencia (Spain) Case Study.

The aim of the present study was to evaluate the relative attenuation of VIS, UV and NIR solar radiation through a large pond skylight into the interior of the l'Almoina Archaeological Museum (Valencia, Spain), and to determine how relative attenuation varied throughout the year and time of day. Measurements were taken at 9:00 a.m.
