  Title Improving accuracy of economic estimations with VIIRS DNB image products Type Journal Article
  Year 2017 Publication International Journal of Remote Sensing Abbreviated Journal International Journal of Remote Sensing  
  Volume 38 Issue 21 Pages 5899-5918  
  Keywords Remote Sensing  
  Abstract A new-generation of night-time lights (NTL) image products, the Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) monthly composites, have been produced and released by the National Oceanic and Atmospheric Administration’s National Centers for Environmental Information. Compared with the last generation NTL image products, the Defense Meteorological Satellite Program’s Operational Linescan System stable light composites, the new NTL image products have finer spatial resolution with compatible radiance values across different month/year images. However, the current defects in VIIRS DNB monthly composites show ephemeral lights, relatively high radiance in winter months, and missing data over the high-latitude regions of the northern hemisphere in summer months. This study presents a method to improve the accuracy of the new NTL image products by statistically modelling the time series VIIRS NTL images and uses the improved imagery to estimate socio-economic factors. In this method, we first estimate radiance for each pixel with ‘no data’ in May, June, July, and August images and then exponentially smooth the monthly time series images to produce a 2014 annual VIIRS DNB image for the contiguous USA. Sum radiance derived from the smoothed annual image shows stronger correlations with gross domestic product at the state level and smaller standard errors of the estimate at the metropolitan and county levels compared with that extracted from the annual image produced by simply averaging the original monthly DNB composites. Such results infer that exponential smoothing effectively improves the quality of the VIIRS DNB images for annual economic estimation.

  Title Urban mapping using DMSP/OLS stable night-time light: a review Type Journal Article
  Year 2017 Publication International Journal of Remote Sensing Abbreviated Journal International Journal of Remote Sensing  
  Volume 38 Issue 21 Pages 6030-6046  
  Keywords Remote Sensing; Review  
  Abstract The Defense Meteorological Satellite Program/Operational Linescane System (DMSP/OLS) stable night-time light (NTL) data showed great potential in urban extent mapping across a variety of scales with historical records dating back to 1990s. In order to advance this data, a systematic methodology review on NTL-based urban extent mapping was carried out, with emphases on four aspects including the saturation of luminosity, the blooming effect, the intercalibration of time series, and their temporal pattern adjustment. We think ancillary features (e.g. land surface conditions and socioeconomic activities) can help reveal more spatial details in urban core regions with high digital number (DN) values. In addition, dynamic optimal thresholds are needed to address issues of different exaggeration of NTL data in the large scale urban mapping. Then, we reviewed three key aspects (reference region, reference satellite/year, and calibration model) in the current intercalibration framework of NTL time series, and summarized major reference regions in literature that were used for intercalibration, which is critical to achieve a globally consistent series of NTL DN values over years. Moreover, adjustment of temporal pattern on intercalibrated NTL series is needed to trace the urban sprawl process, particularly in rapidly developing regions. In addition, we analysed those applications for urban extent mapping based on the new generation NTL data of Visible/Infrared Imager/Radiometer Suite. Finally, we prospected the challenges and opportunities including the improvement of temporally inconsistent NTL series, mitigation of spatial heterogeneity of blooming effect in NTL, and synthesis of different NTL satellites, in global urban extent mapping.

  Title Outdoor light and breast cancer incidence: a comparative analysis of DMSP and VIIRS-DNB satellite data Type Journal Article
  Year 2016 Publication International Journal of Remote Sensing Abbreviated Journal International Journal of Remote Sensing  
  Volume 38 Issue 21 Pages 5952-5961  
  Keywords Human Health  
  Abstract Several population-level studies explored the association between breast cancer (BC) incidence and artificial light-at-night (ALAN), and found higher BC rates in more lit areas. Most of these studies used ALAN satellite data, available from the United States Defence Meteorological Satellite Program (US-DMSP), while, in recent years, higher-resolution ALAN data sources, such as Visible Infrared Imaging Radiometer Suite Day-Night Band (VIIRS-DNB), have become available. The present study aims to determine whether the use of different ALAN data sources may affect the BC–ALAN association. As the test case, we use data on BC incidence rates in women residing in the Greater Haifa Metropolitan Area (GHMA; Israel), matching them with US-DMSP and VIIRS-DNB data on ALAN intensities, and controlling for several potential confounders, including age, fertility, and socio-economic status (SES). Both ordinary least squares (OLS) and spatial dependency models were used in the analysis. ALAN emerged as a stronger predictor of BC rates in models based on better-resolution VIIRS-DNB estimates (t > 6.035; p < 0.01) than in models based on coarser US-DMSP data (t < 4.196; p < 0.01).

  Title Mapping geographical concentrations of economic activities in Europe using light at night (LAN) satellite data Type Journal Article
  Year 2014 Publication International Journal of Remote Sensing Abbreviated Journal International Journal of Remote Sensing  
  Volume 35 Issue 22 Pages 7706-7725  
  Keywords Remote Sensing  
  Abstract Data on geographical concentrations of economic activities, such as manufacturing, construction, wholesale and retail trade, financial services, etc., are important for identifying clusters of economic activities (EAs) and concentrations of forces behind them. However, such data are essentially sparse due to limited reporting by individual countries and administrative entities. For example, at present, Eurostat provides EA data for <50% of all regional subdivisions of the third tier of the Nomenclature of Territorial Units for Statistics (NUTS3). Measurements of light at night (LAN), as captured by satellite sensors, are likely to differ in intensity, depending on the source. As a result, LAN levels can become a marker for EAs; the present study attempts to verify this possibility. As the present analysis indicates, the inclusion of LAN intensities in multivariate models (in addition to standard economic and locational variables) helps to explain up to 88.8% of the EA variation, performing especially well for manufacturing, construction, and agriculture (the adjusted coefficient of determination (R2-adjusted) is in the range of 0.754–0.888). The study thus confirms the feasibility of using LAN satellite measurements for reconstructing geographical patterns of EAs, information that may be restricted or is unavailable due to sparse or incomplete reporting.

  Title Brazil's 2001 energy crisis monitored from space Type Journal Article
  Year 2004 Publication International Journal of Remote Sensing Abbreviated Journal International Journal of Remote Sensing  
  Volume 25 Issue 12 Pages 2475-2482  
  Keywords Remote Sensing; Energy  
  Abstract Data sensed by the US Air Force Defence Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) during the years 2000 and 2001 in Brazil were tested as a tool to monitor reduction of nocturnal lighting. This particular timing was examined as the Brazilian population and industry were forced to reduce electric power consumption by 20% during 2001, in relation to 2000, for a period of several months, starting officially on 1 June 2001. Large urban agglomerates were compelled to switch off city lights by at least the same amount. The Distrito Federal (DF), including the Brazilian capital, Brasilia, was one of the primary areas where the government actively sought electric power consumption reductions. Using the DF as a study case, we demonstrate that the mean grey levels derived from averaging DMSP-OLS data acquired over urban centres appear to be a useful index to monitor relative oscillations in energy consumption.
