Title Identifying and mapping night lights using imaging spectrometry Type Journal Article
Year 2011 Publication Proceedings of Aerospace Conference, 2011 IEEE, March 5-11 2011. Abbreviated Journal
Volume Issue (up) Pages 1 - 6
Keywords Instrumentation
Abstract Remote mapping of night lights using the Defense Meteorological Satellite Program (DMSP) has been used for decades to inventory the global distribution of human activity. ©± The coarse spatial and spectral resolution of DMSP, however, has precluded discrimination of lighting types or spectral characteristics. Recent demonstrations using photography from the International Space Station and airborne multispectral simulations demonstrate significant potential, but high-spectral-resolution field and laboratory measurements indicate that these methods do not take full advantage of the spectral information available. This research demonstrates the use of imaging spectrometer data to identify, characterize, and map urban lighting based on comparison to a lights spectral library. The library provides information about spectral emission lines unique to specific lighting types. ProSpecTIR-VS imaging spectrometer data of Las Vegas, Nevada were analyzed to extract spectral features and these were compared to the spectral library measurements on a pixel-by-pixel basis, resulting in a detailed spatial map showing different lighting types. The nature and distribution of lights can be used as a surrogate for characterization of urban settings, and measurement of urban development.

Title Measuring the Night Sky Brightness with the Lightmeter. Type Journal Article
Year 2011 Publication ReVMexAA Abbreviated Journal
Volume 41 Issue (up) Pages 46–49
Keywords Instrumentation; instrumentation: photometers; light pollution; methods: data analysis; methods: observational; site testing
Abstract We present a newly developed, low-cost photometer for long-term monitoring of the night sky brightness and

light pollution on Earth. The so-called Lightmeter is an as far as possible stand-alone operational, fully

weatherproof, and maintenance-free device. It provides a high data sampling rate of up to 1 Hz as well as a

superb sensitivity covering the whole brightness range down to the darkest night time conditions. The excellent

performance of the Lightmeter allows a continuously monitoring of the night sky brightness and opens a wide

range of applications at an observatory site like determining overall sky conditions in real time, cloud detection

and estimation of their velocity, measuring relative changes in extinction as well as the detection of long term

trends in brightness caused by an increase of artificial illumination. We will present first results of measurements

taken at Cerro Armazones, one of the best obser

Title Night Sky Photometry with Sky Quality Meter Type Journal Article
Year 2005 Publication Technical Report 9, ISTIL. V1.4. Abbreviated Journal
Volume Issue (up) Pages
Keywords Instrumentation; light pollution; night sky brightness; photometry; instruments; calibration
Abstract Sky Quality Meter, a low cost and pocket size night sky brightness photometer, opens to the general public the possibility to quantify the quality of the night sky. Expecting a large diffusion of measurements taken with this instrument, I tested and characterized it. I analyzed with synthetic photometry and laboratory measurements the relationship between the SQM photometrical system and the main systems used in light pollution studies. I evaluated the conversion factors to Johnson’s B and V bands, CIE photopic and CIE scotopic responses for typical spectra and the spectral mismatch correction factors when specific filters are added.
