Title (up) Assessment of Light Pollution Based on the Analysis of Luminous Flux Distribution in Sports Facilities Type Journal Article
Year 2019 Publication Engineer of the XXI Century Abbreviated Journal
Volume 70 Issue Pages 139-150
Keywords Lighting
Abstract The article attempts to assess the amount of light pollution with artificial light from sports facilities. The football stadium has been analysed, while considering a few configurations that take into account different coefficients of reflection of the luminous flux for the tribunes and the object main board. Simplified model of the football stadium was introduced to the DIALux simulation software, and then computer calculations were made for selected variants. In addition, the applicable normative requirements in the field of lighting systems were discussed and the mathematical distribution of the luminous flux in the examined sports facility was presented.

Title (up) Assessment of outdoor lighting installations and their impact on light pollution using unmanned aircraft systems – The concept of the drone-gonio-photometer Type Journal Article
Year 2020 Publication Journal of Quantitative Spectroscopy and Radiative Transfer Abbreviated Journal Journal of Quantitative Spectroscopy and Radiative Transfer

Keywords Instrumentation; Lighting
Abstract This paper presents the ongoing work of the lighting laboratory to develop a standardized method for the measurement of several types of lighting installations using unmanned aircraft systems. The technology of unmanned aircraft systems can incorporate multiple types of sensors and can be programmed to fly in predefined areas and routes in order to perform complex measurements with limited human intervention. This technology provides the freedom of measurements from several angular positions and altitudes in a fast, easy, accurate and repeatable way. The overall aim of this work is to assess the lighting installations, not only against the applicable lighting standards but also to investigate and reveal issues related to light pollution and obtrusive lighting. The latter are issues that in most cases are neglected due to the lack of standardized methods of calculation and measurement. Current assessment methods require illuminance or luminance measurements of horizontal and vertical surfaces generally from the ground. The proposed approach provides a holistic three-dimensional evaluation of the lighting installations beyond the common methods and geometries and opens the discussion for future update of the relevant standards on outdoor lighting. In the scope of this paper, several proof-of-concept cases are presented.

Title (up) Assessment of the impact of the 2010 Haiti earthquake on human activity based on DMSP/OLS time series nighttime light data Type Journal Article
Year 2019 Publication Journal of Applied Remote Sensing Abbreviated Journal J. Appl. Rem. Sens.
Volume 13 Issue 04 Pages 1
Keywords Remote Sensing
Abstract Earthquake disasters and postdisaster reconstruction have profound impacts on human society. We use time series nighttime light images collected by the defense meteorological satellite program-operational linescan system sensors as a proxy data source for human activities (HAs). After calibration, a time series analysis method is used to study the distribution and intensity of the changes in HAs after an earthquake. We consider the Haiti earthquake an example to analyze the HA sequence patterns and the aggregation patterns of the HA centers. The results show the following: (1) postearthquake recovery and reconstruction efforts led to increases in the long-term HAs, but the level of increased HA was usually low. (2) The level of postearthquake HAs in the most affected areas (seismic intensity zone VIII+) increased, whereas the postearthquake HAs in severely affected areas (seismic intensity zones VI and VII) were more fragmented. (3) The recovery of HAs in seismic intensity zone VIII+ (mainly Port-au-Prince) required 2 years, but the actual time may be far longer.

Title (up) Asset exposure data for global physical risk assessment Type Journal Article
Year 2020 Publication Earth System Science Data Abbreviated Journal Earth Syst. Sci. Data
Volume 12 Issue 2 Pages 817-833
Keywords Economics
Abstract One of the challenges in globally consistent assessments of physical climate risks is the fact thatasset exposure data are either unavailable or restricted to single countries or regions. We introduce a globalhigh-resolution asset exposure dataset responding to this challenge. The data are produced using “lit population”(LitPop), a globally consistent methodology to disaggregate asset value data proportional to a combination ofnightlight intensity and geographical population data. By combining nightlight and population data, unwantedartefacts such as blooming, saturation, and lack of detail are mitigated. Thus, the combination of both data typesimproves the spatial distribution of macroeconomic indicators. Due to the lack of reported subnational assetdata, the disaggregation methodology cannot be validated for asset values. Therefore, we compare disaggregatedgross domestic product (GDP) per subnational administrative region to reported gross regional product (GRP)values for evaluation. The comparison for 14 industrialized and newly industrialized countries shows that thedisaggregation skill for GDP using nightlights or population data alone is not as high as using a combinationof both data types. The advantages of LitPop are global consistency, scalability, openness, replicability, and lowentry threshold. The open-source LitPop methodology and the publicly available asset exposure data offer valuefor manifold use cases, including globally consistent economic disaster risk assessments and climate changeadaptation studies, especially for larger regions, yet at considerably high resolution. The code is published onGitHub as part of the open-source software CLIMADA (CLIMate ADAptation) and archived in the ETH DataArchive with the link https://doi.org/10.5905/ethz-1007-226 (Bresch et al., 2019b). The resulting asset exposuredataset for 224 countries is archived in the ETH Research Repository with the link https://doi.org/10.3929/ethz-b-000331316 (Eberenz et al., 2019).
