Title Assessing Public Perceptions about Road Lighting in five Neighborhoods of Tirana, Albania Type Journal Article
Year 2019 Publication (up) Abbreviated Journal
Volume Issue Pages
Keywords Psychology
Abstract Lighting is essential for sight, human health and well-being, emerging the need for assessing exterior lighting to better understand how far public is satisfied about exterior lighting. Exterior lighting was assessed in five major roads of the capital city of Tirana, Albania, in November 2017. Security, obstacle detection and visibility were evaluated using questionnaires for road lighting. The approximately 87 and 60 percent of respondents, respectively, were not able to detect a pavement obstacle after-dark and to distinguish a

familiar face at a distance of 5 m and 10 m along roads. Road lighting after-dark was unsatisfactory to 60 percent of respondents. These findings identified road lighting could be inadequate for users, requiring further investigation and new data collection of road lighting in neighborhoods of Tirana.

Title LOCALIZED LIGHT SENSORY IN RELATION TO GRAZING ACTIVITY OF ECHINOMETRA MATHAEI Type Journal Article
Year 2018 Publication (up) Abbreviated Journal
Volume Issue Pages
Keywords Animals
Abstract This paper offers insight on the regulation of nocturnal behavior in burrowing sea urchin Echinometra mathaei of the Pacific. While it is known E. mathaei maintains nocturnal hours of activity (primarily grazing, burrowing, and locomotion), it is unknown whether this pattern follows a circadian rhythm or responds to local conditions of darkness. Varying light treatments were tested to determine potential manipulation of active behavior and explore potential for habitat destruction. Light manipulation was used to determine the role light sensory plays in the regulation of normal behavior. First utilizing gradual manipulation and later utilizing sudden manipulation to differentiate response to light stimuli. It was determined that while E. mathaei maintains nocturnal

activity via localized light sensory, manipulation of latent hours could not be significantly reproduced. It was found that while light manipulation can be responsible for simulating hours of activity, light manipulation cannot replicate latent hours. Upon exploration of predator response capability in E. mathaei following manipulation, it was found that individuals exposed to prolonged periods of artificial light had slower predation response times than individuals acclimated to a regular pattern of light exposure. These findings connect potential habitat degradation via grazing behaviors of E. mathaei to anthropogenic activity in Mo’orea, French Polynesia.

Title Licht über Wien V Type Journal Article
Year 2017 Publication (up) Abbreviated Journal
Volume Issue Pages
Keywords Skyglow
Abstract Die hier präsentierte Studie gibt einen detaillierten Überblick zur Entwicklung derLichtverschmutzung über dem Stadtgebiet von Wien in den Jahren 2011 bis 2017 und bietet einePrognose bis 2020. Damit ist international erstmals eine Langzeitstudie über die Entwicklung derLichtverschmutzung einer Großstadt verfügbar. Im Rahmen der begleitenden Untersuchungen sindAussagen über die Verursacher und ihre spezifischen Anteile an der Lichtverschmutzung Wiensmöglich. Die aktuelle Umrüstung auf LED-Technik wird diskutiert und findet Eingang in diePrognose. Neue Messungen und Analysen von internationalen Teams werden kurz vorgestellt undbezüglich ihrer Relevanz vergleichend mit unserer Studie diskutiert.

Title Licht über Wien VI Type Journal Article
Year 2018 Publication (up) Abbreviated Journal
Volume Issue Pages
Keywords Skyglow
Abstract Im Zentrum Wiens sättigt die Erhellung der Nacht, am Stadtrand sinken die jährlichen Zuwächse, wäh-rend im Abstand von 36 Kilometern (Großmugl) die Nächte um 10 % pro Jahr heller werden.Der Gesamtaufwand der Wiener Lichtglocke liegt 2018 bei 37 MW. Der Verlauf von 2011 bis 2018 zeigt ein deutliches Lichtmaximum um 2014 und 2015. Danach stellen wir einen allmählichen Rückgang fest.Der Verlauf der Lichtglocke und noch deutlicher jener der Einzelstationen zeigt signifikante Schwankun-gen von Jahr zu Jahr. Zur Aufklärung der Ursachen, die weder astronomisch noch meteorologisch sind, wur-den monatliche Analysen des Lichtmessnetzes mit Daten des Luftmessnetzes der Wiener MA 22 kombiniert. Die natürliche Variation über das Jahr wurde genutzt, um Zusammenhänge zwischen den Monatsmedianen von Luftfeuchtigkeit und Feinstaub mit jenen der Globalstrahlungsdaten zu suchen.Von 2016 bis 2018 korrelieren die Globalstrahlungswerte mit der relativen Luftfeuchtigkeit und den Feinstaubwerten (PM10 und PM2,5). Die engste Beziehung besteht auf der Kuffner-Sternwarte, wo eine Verdoppelung der Luftfeuchtigkeit statistisch von einer Verzehnfachung der Globalstrahlung begleitet wird. Die gefundenen Relationen sind über einen Faktor 100 in der Globalstrahlung äußerst robust und die Koeffizienten der Relationen sind an allen Stationen sehr homogen.Damit stehen gut bestimmte Zusammenhänge zwischen der Luftgüte und dem Zustand der klaren Atmo-sphäre zur Verfügung. Das wird es erlauben, Lichtmessnetze auf Standardatmosphären zu beziehen und damit eine wesentlich bessere Vergleichbarkeit der Daten zu unterschiedlichen Zeitpunkten herzustellen.- 130 Gigawattstunden Jahresaufwand für die Wiener Lichtglocke- 8 Jahre Vermessung der Lichtglocke zeigen Ansätze eines Rückgangs der Lichtflut- Mehr Feinstaub bewirkt überproportional mehr Lichtverschmutzung

Title A Year in Space for the CUbesat MULtispectral Observing System: CUMULOS Type Conference Article
Year 2019 Publication (up) 33rd Annual AIAA/USU Conference on Small Satellites Abbreviated Journal
Volume SSC19-XI-01 Issue Pages
Keywords Remote Sensing
Abstract CUMULOS is a three-camera system flying as a secondary payload on the Integrated Solar Array and Reflectarray Antenna (ISARA) mission with the goals of researching the use of uncooled commercial infrared cameras for Earth

remote sensing and demonstrating unique nighttime remote sensing capabilities. Three separate cameras comprise the CUMULOS payload: 1) a visible (VIS) Si CMOS camera, 2) a shortwave infrared (SWIR) InGaAs camera, and 3) a longwave infrared (LWIR) vanadium oxide microbolometer. This paper reviews on-orbit operations during the past year, in-space calibration observations and techniques, and Earth remote sensing highlights from the first year of space

operations. CUMULOS operations commenced on 8 June 2018 following the successful completion of the primary ISARA mission. Some of the unique contributions from the CUMULOS payloads include: 1) demonstrating the use of bright stars for on-orbit radiometric calibration of CubeSat payloads, 2) acquisition of science-quality nighttime lights data at 130-m resolution, and 3) operating the first simple Earth observing infrared payloads successfully flown on a CubeSat. Sample remote sensing results include images of: cities at night, ship lights (including fishing vessels), oil industry gas flares, serious wildfires, volcanic activity, and daytime and nighttime clouds. The CUMULOS VIS camera has measured calibrated nightlights imagery of major cities such as Los Angeles, Singapore, Shanghai, Tokyo, Kuwait City, Abu Dhabi, Jeddah, Istanbul, and London at more than 5x the resolution of VIIRS. The utility of these data for measuring light pollution, and mapping urban growth and infrastructure development at higher resolution than

VIIRS is being studied, with an emphasis placed on Los Angeles. The “Carr”, “Camp” and “Woolsey” fires from the 2018 California fire season were imaged with all three cameras and results highlight the excellent wildfire imaging

performance that can be achieved by small sensors. The SWIR camera has exhibited extreme sensitivity to flare and fire hotspots, and was even capable of detecting airglow-illuminated nighttime cloud structures by taking advantage of the strong OH emissions within its 0.9-1.7 micron bandpass. The LWIR microbolometer has proven successful at providing cloud context imagery for our nightlights mapping experiments, can detect very large fires and the brightest flare hotspots, and can also image terrain temperature variation and urban heat islands at 300-m resolution. CUMULOS capabilities show the potential of CubeSats and small sensors to perform several VIIRS-like nighttime mission areas in which wide area coverage can be traded for greater resolution over a smaller field of view. The sensor

has been used in collaboration with VIIRS researchers to explore these mission areas and side-by-side results will be presented illustrating the capabilities as well as the limitations of small aperture LEO CubeSat systems.
