Der Zustand der Nacht 2021 - Milchstraße, Kunst- und Sternlicht, strategische Projekte der Kuffner-Sternwarte
Günther Wuchterl, Verein Kuffner-Sternwarte und Naturhistorisches Museum Wien
Mit der Rettung der Kuffner-Sternwarte in den 1990ern begann der "Verfall" des Nachthimmels dramatische Ausmaße anzunehmen. Strategien und Projekte zur Bewusstseinsbildung, des Monitoring und der Ursachenerfassung der Lichtverschmutzung entstanden auf der Sternwarte. Mit ersten Interventionen und dem großen Wiener Lichttausch begannen die Schritte zur "Lichtwende" und ihre wissenschaftliche Begleitung gemeinsam mit der Stadt Wien, der Gemeinde Großmugl und den Österreichischen Welterbe Partnern. Die Strategie und die wissenschaftlichen Methoden werden skizziert und eine Ergebnis-Synopsis wird gegeben.

Der Vortrag bietet einen Überblick über das im Jahr 2010 gegründete ARAD Messnetz.
Marc Olefs ist studierter Meteorologe und leitet seit 2018 die Abteilung für Klimaforschung an der Zentralanstalt für Meteorologie und Geodynamik (ZAMG) in Wien. Seine Forschungsinteressen liegen in den Bereichen Monitoring und Modellierung der Sonnen- und Wärmestrahlung sowie der alpinen Schneedecke und im Prozessverständnis der globalen Erwärmung und Gebirgsklimatologie im Alpenraum.
Der Vortrag bietet einen Überblick über das im Jahr 2010 gegründete ARAD Messnetz. ARAD („Austrian Radiation“ – Österreichische Strahlung) ist ein Projekt zur langfristigen Messung der Sonnenstrahlung und der Wärmestrahlung der Atmosphäre in Österreich. Derzeit werden an 6 Standorten (Wien Hohe Warte, Sonnblick, Graz, Innsbruck, Kanzelhöhe, Klagenfurt) die zeitlichen und räumlichen Änderungen der Strahlungskomponenten mit sehr genauen Messgeräten erfasst.

Außenbeleuchtung und Dark Skies - Die Implementierung des ersten österreichischen Sternenparks Attersee-Traunsee
Stefan Wallner ist Astrophysiker an der Universität Wien sowie der Slowakischen Akademie der Wissenschaften. Seit einigen Jahren ist er Projektleiter zur Thematik “Lichtverschmutzung” und forscht insbesondere über Messmethoden sowie Modellierung des Phänomens sowie die verbundene Atmosphärenphysik.”
Künstliches Licht bei Nacht und Umweltschutz müssen keinerlei als Gegensätzlichkeit betrachtet werden. Eine optimale Installation bietet Möglichkeiten die Natürlichkeit des Nachthimmels zu erhalten und nachhaltige Außenbeleuchtung zu betreiben. Dies zeigen insbesondere “Nachtlandschaftsschutzgebiete”, sogenannte International Dark Sky Places. Die International Dark Sky Association (kurz: IDA) bietet dafür mehrere Kategorien der Zertifizierung an, darunter die Kategorie eines „Dark Sky Parks“. Sie vergibt diese Titel an Gebiete, die bestimmte Schritte zum Schutze des Nachthimmels sowie der Verwendung einer optimalen Beleuchtung setzen. Der Vortrag handelt von der Implementierung des ersten österreichischen Dark Sky Parks “Naturpark Attersee-Traunsee” und zeigt, welche Schritte zur Etablierung nötig waren, welche Kriterien der Park einhält, wie es um die Nachthimmelsqualität im Gebiet steht und gibt einen Ausblick in die Zukunft.

The ESO sky background model, with an emphasis on the treatment of scattered moonlight
Amy Jones currently a staff scientist in the instruments division at the Space Telescope Science Institute (STScI), working on HST/STIS. I received my PhD in physics from the University of Innsbruck and have lately done research in sky background modeling and subtraction, and galaxy evolution, and am part of SDSS-IV MaNGA and SDSS-V LVM.
Understanding the sky background is important for many astronomy applications including light pollution. I will introduce the ESO sky background model, with an emphasis on the treatment of scattered moonlight. I will also discuss how to use scattered moonlight to probe the properties of the atmosphere like aerosols. Lastly, I will show how sky background modeling can be used to improve light pollution studies.

Feinstaub und Lichtverschmutzung: "Dicke Luft" macht die Nächte heller
Markus Reithofer, ausgebildeter Chemiker, seit 1984 an der Kuffner-Sternwarte tätig, arbeitet als selbstständiger Fachjournalist und beschäftigt sich seit 2008 mit der messtechnischen Erfassung von Effekten rund um das Thema Lichtverschmutzung. Beteiligung am Aufbau eines Messnetzwerkes und mehrere Publikationen zur Entwicklung der Nachthimmelshelligkeit im Auftrag der Gemeinde Wien.
Die Entstehung, dynamische Verteilung und gesundheitliche Auswirkung von Feinstaub ist gut erforscht. Im Gegensatz dazu steht ein tieferes Verständnis des Phänomens Lichtverschmutzung noch an den Anfängen. Eine die Daten von zehn Jahren umfassende Studie hat gezeigt, welche Zusammenhänge es zwischen verschiedenen Luftgütefaktoren und der Helligkeit des Nachthimmels über dem Großraum der Stadt Wien gibt. Im Vortrag wird insbesondere auf die Korrelationen zweier Feinstaubfraktionen mit der gemessenen Helligkeit, mögliche physikalische Erklärungen und gesundheitliche Seiteneffekte eingegangen.

A new approach to modelling light from urban areas: where it comes from and where it goes (shorter: A LiDAR-based approach to modelling light from urban areas)
Brian Espey is an Associate Professor in the School of Physics, Trinity College Dublin and has been researching in the field of light pollution since 2009. Brian’s background is as an amateur, then professional astronomer, and has used both ground and space observatories, participating in the Astro-2 space shuttle mission. His last position was as a European Space Agency instrument scientist for the STIS instrument on the Hubble Space Telescope. Brian is heavily involved in outreach work both with the public and professional bodies and supports Irish dark sky preservation initiatives. In 2020 Brian was awarded the Dr. Arthur Hoag and William T. Robinson Award by the International Dark Sky Association in recognition of his work in educating governmental organizations, businesses, and the public about the merits of outdoor lighting control ordinances and has worked with Georgia MacMillan and others to develop an integrated environmentally-friendly lighting plan for Newport on the edge of Mayo Dark Sky Park in the West of Ireland. Brian is also a co-founder of Dark Sky Ireland, an activist group campaigning for dark skies preservation.
An important topic of light pollution research is to quantify light loss and permit intercomparison between both ground- and space-based observations. For large cities there are many uncertainties and a statistical approach using simple analytical models has been used previously. I have developed a novel and efficient model that uses LiDAR data together with public lighting databases to predict both the effect of obstructions including buildings and trees on how light escapes to the environment. I will compare the outputs of this work with emission functions developed by others and also with observations at a range of resolutions.
