Lichtemissionen

Darstellung der zeitlichen Entwicklung der Lichtemissionen (Jahreskarten, Monatskarten) in den letzten Jahren anhand von Satellitendaten (VIIRS). Datenquelle: Earth Observation Group, Payne Institute for Public Policy Anmerkung Neben möglicher saisonaler Unterschiede (in erster Linie eine vorhandene Schneedecke), ist auch das teilw. Fehlen des Blauanteils und der Zeitpunkt der Aufnahme bei der Interpretation zu berücksichtigen. Auszug aus dem technischen Bericht Artificial lighting and Biodiversity in Switzerland (p. 11):"Like the DMSP data, VIIRS night time data is panchromatic, representing emissions between 0.5 and 0.9 um (Miller 2013). In effect, it is blind to blue parts of the visible light spectrum, but its on-board radiance calibration means that the reported pixel values are a reliable indication of emissions in the green and red wavelengths. Its low-light sensitivity is reported as ~2E-11 Watts/cm2/sr (Elvidge et al. 2013), and unlike the DMSP data it does not saturate in heavily lit areas such as urban cores. Data collection is at ~01:30, so unfortunately this misses the expected evening peak in urban emissions, but likely captures lights that are present throughout the night."
