Developed to start simple, global continuous high cadence monitoring of night sky brightness and artificial night sky brightening (light pollution) in 2009. The lightmeter network is a project of the Thüringer Landessternwarte, Tautenburg, Germany and the Kuffner-Sternwarte society at the Kuffner-Observatory, Vienna, Austria. It started as part of the Dark Skies Awareness cornerstone of the International Year of Astronomy.http://lightmeter.astronomy2009.athttps://dc.g-vo.org/lightmeter/q/weather/infoIsServedByGAVO Data Center TAP service This database of lightmeter measurements is made available under the Open Database License: http://opendatacommons.org/licenses/odbl/1.0/.
