The DMSP sensors collected sufficient nighttime data worldwide for annual nighttime lights product generation as long as the overpass occurred later than 19:30. DMSP/OLS image, and obtained a relatively accurate city boundary, but the process was too cumbersome(Gu, Gui, 2010. 10. Since the 1990s, many studies have taken advantage of the DMSP/OLS sensor, to monitor artificial lights from space and to quantify the relationships between human activity and socio-economic variables and night-time brightness. Mapping city lights with nighttime data from the DMSP Operational Linescan System. The Operational Linescan System (OLS) flown on the Defense Meteorological Satellite Program (DMSP) satellites, has a unique capability to record low light imaging data at night worldwide. The first of two VIIRS DNB-based datasets is a daily, top-of-atmosphere, at-sensor nighttime radiance product called VIIRS/NPP Daily Gridded Day Night Band 15 arc-second Linear Lat Lon Grid Night. Credit: Levin, et al., 2020 (doi:10.1016/j.rse.2019.111443). NASA’s Black Marble product suite for Suomi NPP (VNP46) improves NTL data in several ways: The Black Marble product suite includes daily at-sensor Top of Atmosphere (TOA) nighttime radiances (VNP46A1), including all necessary ancillary data (e.g., nighttime cloud, snow mask, and view-illumination angles), as well as daily moonlight-adjusted NTL with corresponding quality flags (VNP46A2). The VIIRS Level 1 DNB product has been calibrated, but stray light and other sources of noise (e.g., lunar illuminance, twilight, clouds, noisy scan-edges, etc.) DATA DEVELOPMENT Night light images of the DMSP/OLS, road data (lines), building data (polygons) and grid data of dynamic population were aggregated into same spatial units (1km square grid). The background noise was identified and replaced with values of zero. - Rupert Brooke. Often, these events are followed by power outages and blackouts. These data are archived at the National Oceanic and Atmospheric Administration (NOAA) National Geophysical Data Center (NGDC). thus each satellite provides global coverage of both day night time conditions each day. Also, it’s important to note that the program calls files alphabetically. The DMSP night lights data used in economics are old and not very accurate. For example, with moonlight the reflectance of snow cover, smoke, airborne dust, sea ice, and land surface features are visible. Developed for the detection of clouds using moonlight. Román M.O., Stokes E.C., Shrestha R., Wang Z., Schultz L., Carlo E.A.S., et al. The inclusion of the percent frequency of detection term normalizes the resulting digital values for variations in the persistence of lighting. Agence Française de Développement (AFD) funded the research for the extended DMSP series. The digital stream of data, however, did not begin until 1992. A limited set of observations have been obtained at low lunar illumination were obtained where the gain of the detector was set significantly lower than its typical operational setting (sometimes by a factor of 100). Found inside – Page iThis work analyzes the effects of one of the most dramatic changes of entire societies that the world has ever witnessed. The nighttime light (NTL) data from the Defense Meteorological Satellite Program (DMSP) - Operational Linescan System (OLS) are a primary data source to measure human activities from local . The atmospheric and oceanographic sensors record radiances at visible, infrared and microwave wavelengths.

The first global image was obtained . & Kalb, V. (2018). The VIIRS Plus DMSP Change in Lights (VIIRS+DMSP dLIGHT) data set fuses nighttime lights imagery from the U.S. Air Force Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) with a stable night light composite from the next generation Suomi National Polar-orbiting Partnership (NPP) Visible Infrared Imaging . However, the raw data cannot be used directly for temporal analyses due to the lack of inflight calibration. NASA Worldview image. The spatial resolution is 30x30 arc-second (about 1x1 km) across the globe between 75 degrees north and 65 degrees south. In Aleppo, Syria, the impact of conflict and population displacement that began in early 2013 is seen as a dramatic decrease in nighttime lights (top graph). The second includes these data if the radiance values have undergone the stray-light correction procedure (Reference). Nighttime images of the Earth at night have been obtained from the Defense Metereological Satellite Program (DMSP) of the US Air Force since early '70. DMSP-OLS intercalibration (10 min)¶ As described in Introduction to nighttime light data (20 min), the DMSP-OLS sensors lacked on-board calibration, so there are noticeable variations from satellite to satellite.In order to adequately compare nighttime lights data across satellites, they must be calibrated. Acta Geographica Sinica, 2003, 58(6): 893-902. This requires that the data be carefully processed so scientific analyzes and applications are conducted consistently. The Earth Observations Group (EOG) is producing a version 1 suite of average radiance composite images using nighttime data from the Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB). Unfortunately, accurate monitoring of urban regions is apt to be hampered due to the shortages of the DMSP/OLS data. Lights in the center half have better geolocation, are smaller, and have more consistent radiometry. The data image in the title graphic shows the Earth's city lights at night, from data from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS). gdal_translate.exe -of GTiff

Found inside – Page iiiThis book offers an analysis of the leading missions in global Earth observation, and reviews the main fields in which remote sensing methods are providing vital data for global change studies. The U.S. Department of Defense launched the Defense Meteorological Satellite Program (DMSP), a series of sun-synchronous satellites, to collect nighttime light emissions with the Operational Linescan System (OLS) sensor from the early 1970s until 2011. As population grows and urbanization increases, cities and humans encroach on natural environments. These sources include moonlight, light directly emitted by a source (e.g., buildings and transport), and light reflected by the ground, also known as surface albedo. In 2002, North Korea passed market liberalization reforms that allowed market forces to determine food prices. (OLS) has a unique capability to detect visible and near-infrared (VNIR) Black Marble HD is generated through the synergistic use of the daily NASA Black Marble standard product with data from other Earth observing satellites (e.g., Landsat 8, Sentinel-2) and ancillary data sources (e.g., street, building, and other GIS layers). ephemeral events, such as fires. The original global nighttime lights time series from DMSP was produced using OLS data from six individual satellites (Figure 1). Suomi NPP satellite now provides almost a decade of daily observations of night light. The interest for the protection of the night sky from light pollution is growing every day. DMSP data collected by US Air Force Weather Agency. Found inside – Page 1Abstract: While the incidence of extreme poverty in China fell dramatically over 1980-2001, progress was uneven over time and across provinces. The presence of nighttime snow also enhances the scattering of reflected NTL due to the increased surface reflectance. Radiance Light Trends is a software for selecting regions of Earth and examining the trend in light emissions observed by satellite. The Defense Meteorological Satellite Program Operational Linescan System (DMSP-OLS) stable night-time light data and Suomi National Polar-orbiting Partnership Visible Infrared Imaging Radiometer Suite (NPP-VIIRS) nighttime light data are two widely used NTL datasets. Ecological Consequences of Artificial Night Lighting is the first book to consider the environmental effects of the intentional illumination of the night. The book comprehensively reviews the current knowledge on how natural and anthropogenic land-use/cover changes affect weather, air quality and climate worldwide and explains how these changes may trigger further land-use/cover changes. This inconsistency can cause issues when analyzing time series. These datasets help monitor, track, and compare COVID-19-driven changes to Earth systems over time. The OLS acquires swaths of data that are 3000 km wide.
