![]() Note that the maps report artificial light only! The zenith radiance from natural sources such as stars and the Milky Way are not included, and must be added in order to match the data that would be obtained from an actual outdoor measurement.Ī kmz file for quick view of the data is also provided. 2007 Falchi 2010 Kyba et al 2013, 2015 and Zamorano et al. The upward emission function and the radiance calibration were obtained using data from Sky Quality Meters (including data from Duriscoe et al. 2013), which has been propagated through the atmosphere using the radiative transfer code reported in (Cinzano and Falchi, 2012). The map is based on data from the VIIRS Day Night Band (DNB, MIller et al. The map reports simulated zenith radiance data in. ![]() The data are stored in a 2.9 Gb geotiff file, on a 30 arcsecond grid. AbstractThese are maps of artificial night sky radiance that were produced by the Light Pollution Science and Technology Institute (ISTIL), and described in the paper "The New World Atlas of Artificial Night Sky Brightness" (Falchi et al.
