The website nightsky.univie.ac.at contains data and plots about night sky brightness (mainly in Eastern Austria) from automated SQM measurements at various stations, from Vienna to the Dachstein plateau. Detailed analysis techniques are described in Posch, Binder & Puschnig 2018.
Code and Tools for plot-creation developed by Quellcode GmbH, Zürich.
We calculate night sky brightness trends under clear, moonless conditions by correcting for atmospheric influences and instrument aging, as explained in Puschnig et al. 2023.
