Title Tracking an oil tanker collision and spilled oils in the East China Sea using multi‐sensor day and night satellite imagery Type Journal Article
Year 2018 Publication Geophysical Research Letters Abbreviated Journal
Volume 45 Issue 7 Pages 3212-3220
Keywords Remote Sensing
Abstract Satellite remote sensing is well known to play a critical role in monitoring marine accidents such as oil spills, yet the recent SANCHI oil tanker collision event in January 2018 in the East China Sea indicates that traditional techniques using synthetic aperture radar (SAR) or daytime optical imagery could not provide timely and adequate coverage. In this study, we show the unprecedented value of VIIRS Nightfire product and Day/Night Band (DNB) data in tracking the oil tanker's drifting pathway and locations when all other means are not as effective for the same purpose. Such pathway and locations can also be reproduced with a numerical model, with RMS error of < 15 km. While high‐resolution optical imagery after 4 days of the tanker's sinking reveals much larger oil spill area (> 350 km2) than previous reports, the impact of the spilled condensate oil on the marine environment requires further research.

Title How many bioluminescent insects would be needed to produce the same level of light pollution as London? Type Journal Article
Year 2017 Publication Journal of Interdisciplinary Science Topics Abbreviated Journal
Volume 7 Issue Pages
Keywords Remote Sensing; Lighting; Animals
Abstract This paper determines how many light emitting Pyrophorus noctilucus would be required to produce the same level of light, and so the same amount of light pollution, as London. It was determined that if one P. noctilucos emitted 0.00153 lumens, it would take 2.940x1011 of them to produce the 449x106 lumen emitted by London. This number of bugs equates to an area of approximately 1.911x108 m2 which is 8 times smaller than the size of London.

Title How Much Should We Trust the Dictator's GDP Estimates? Type Journal Article
Year 2018 Publication Abbreviated Journal SSRN
Volume Issue Pages
Keywords Economics; Remote Sensing
Abstract I study the manipulation of GDP statistics in weak and non-democracies. I show that the elasticity of official GDP figures to nighttime lights is systematically larger in more authoritarian regimes. This autocracy gradient in the night-lights elasticity of GDP cannot be explained by differences in a wide range of factors that may affect the mapping of night lights to GDP, such as economic structure, statistical capacity, rates of urbanization or electrification. The gradient is larger when there is a stronger incentive to exaggerate economic performance (years of low growth, before elections or after becoming ineligible for foreign aid) and is only present for GDP sub-components that rely on government information and have low third-party verification. The results indicate that yearly GDP growth rates are inflated by a factor of between 1.15 and 1.3 in the most authoritarian regimes. Correcting for manipulation substantially changes our understanding of comparative economic performance at the turn of the XXI century.

Title What do night satellite images and small-scale grid data tell us about functional changes in the rural-urban environment and the economy? Case studies Frankfurt-Rhein/Main and Ljubljana Urban Region Type Journal Article
Year 2018 Publication Abbreviated Journal
Volume Issue Pages
Keywords Remote Sensing
Abstract This study addresses how nocturnal satellite imagery can be used in spatial analysis of rural-urban relations. It shows how a novel approach can be used to complement the prevalent traditional survey methods below the data resolution level of official regional statistics. The overarching aim is to contribute with a novel database and different empirical tools to broaden spatial information for decision-making in policy and planning at small spatial scale amongst municipalities. The accuracy of spatial information is expected to be substantially enhanced, paving ways for better rural-urban planning coordination and synergies.
