  Title (up) A thirst for development: mapping water stress using night-time stable lights as predictors of province-level water stress in China Type Journal Article
  Year 2017 Publication Area Abbreviated Journal Area  
  Volume 49 Issue 4 Pages 477-485  
  Keywords Remote Sensing  
  Abstract Given the rapid development within China, the inequality of available water resources has been increasingly of interest. Current methods for assessing water stress are inadequate for province‐scale rapid monitoring. A more responsive indicator at a finer scale is needed to understand the distribution of water stress in China. This paper selected Defense Meteorological Satellite Program Operational Line‐scan System night‐time stable lights as a proxy for water stress at the province level in China from 2004 to 2012, as night‐time lights are closely linked with population density, electricity consumption and other social, economic and environmental indicators associated with water stress. The linear regression results showed the intensity of night‐time lights can serve as a predictive tool to assess water stress across provinces with an R2 from 0.797 to 0.854. The model worked especially well in some regions, such as East China, North China and South West China. Nonetheless, confounding factors interfered with the predictive relationship, including population density, level of economic development, natural resource endowment and industrial structures, etc. The model was not greatly improved by building a multi‐variable linear regression including agricultural and industrial indicators. A straightforward predictor of water stress using remotely sensed data was developed.

  Title (up) A Year in Space for the CUbesat MULtispectral Observing System: CUMULOS Type Conference Article
  Year 2019 Publication 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.

  Title (up) Absolute photometry and Night Sky Brightness with all-sky cameras Type Report
  Year 2013 Publication e-prints Complutense Abbreviated Journal e-prints Complutense  
  Volume Issue 24626 Pages  
  Keywords Instrumentation; skyglow; measurement; modeling  
  Abstract All-sky cameras have proven to be powerful tools to continuously monitoring the sky in a wide range of fields in both Astrophysics and Meteorology. In this work, we have developed a complete software pipeline to analyze the night CCD images obtained with one of such systems. This let us to study typical parameters used in Astrophysics to characterize the night sky quality, such as the Sky Brightness, the Cloud Coverage and the Atmospheric Extinction, how they evolve over the time and their variability. Using our software, we analyzed a large set of data from AstMon-OT all-sky camera at Teide Observatory. Results from this work have been applied in the support to the spanish CTA site proposal at Izaña, Tenerife and are being discussed within the CTA consortium. A comparison with data from other devices that have been used in site characterization such as the IAC80 telescope is also presented. This comparison is used to validate the results of the analysis of all-sky images. Finally, we test our software with AstMon-UCM and DSLR cameras. Some general recommendations for the use of DSLR cameras are provided.

  Title (up) Absolute Radiometric Calibration of TESS-W and SQM Night Sky Brightness Sensors Type Journal Article
  Year 2019 Publication Sensors Abbreviated Journal Sensors  
  Volume 19 Issue 6 Pages 1336  
  Keywords Instrumentation; calibration; SQM; TESS; photometer; sky brightness  
  Abstract We develop a general optical model and describe the absolute radiometric calibration of the readings provided by two widely-used night sky brightness sensors based on irradiance-to-frequency conversion. The calibration involves the precise determination of the overall spectral sensitivity of the devices and also the constant G relating the output frequency of the light-to-frequency converter chip to the actual band-weighted and field-of-view averaged spectral radiance incident on the detector (brightness). From these parameters, we show how to define a rigorous astronomical absolute photometric system in which the sensor measurements can be reported in units of magnitudes per square arcsecond with precise physical meaning.

  Title (up) Accessing the economic value of night view of bridge using contingent valuation method: the case of South Korea's Han-River bridge Type Journal Article
  Year 2015 Publication International Journal of Culture, Tourism and Hospitality Research Abbreviated Journal Int. J. of Culture, Tourism and Hospitality Res.  
  Volume 9 Issue 3 Pages 360-370  
  Keywords Economics; South Korea; Korea; Han River Bridge; contingent valuation method; Viewshed analysis; Seoul  
  Abstract Purpose

The purpose of this study is to estimate an individual’s probability of preservation the night view of Han-River Bridge at tax using the CVM; and to present the effects of 4Es on experience economy theory.

Design/methodology/approach

The on-site survey was conducted in the 11 district Han-river parks; Gwangnaru, Jamsil, Ttukseom, Jamwon, Banpo, Yeechon, Yeouido, Mangwon, Nanji, Ganseo and Yanghwa district including 24 bridge ssuch as Banpo, Olympic Bridge during the 8-9pm around the lighting and 9-10pm peak time of lighting.

Findings

Truncated mean WTP indicates that the economic value of the night view of Han-River Bridge is 49,575 won (about U.S. $50) per household, which implies the significance of the preservation value of the night view.

Research limitations/implications

This study sets a hypothetical market and there are limitations on hypothetical bias of the DC CVM. For the future study, a survey with a specific real payment vehicle in an attempt to reduce hypothetical bias can be a tool for the prevention of the overestimation.

Practical implications

Through the study, Seoul city has to invest aggressively on the night view landscape business of Han River bridge, which can become a landmark and lots of attraction effect of tourists. Since this study’s core aim was to justify the economic value of the night-view of the Han-River bridges, the estimated amount strongly supports the lighting business of the Han-River bridge.

Originality/value

The results of this research may help policy makers of Han-River to establish practical decision whether improving and preserving the Han-River’s night view lighting business are worth the value.
