We have produced annual estimates of national and global gas flaring efficiency from 1994 through 2008 using low light imaging data acquired by the Defense Meteorological Satellite Program (DMSP).

We have developed a set algorithms detection spikes characterization sharpness spike features. A generates list...
In this paper, we compare 2015 satellite-derived natural gas (gas) flaring data with the greenhouse reduction targets presented by those countries in their nationally determined contributions (NDC) under United Nations Framework Convention on Climate Change (UNFCCC) Paris Agreement. Converting from to utilization is an attractive option for reducing emissions. The analysis rates potential role of meeting country-specific NDC targets. includes three categories flaring: upstream oil and...

Electric power services are fundamental to prosperity and economic development. Disruptions in the electricity service can range from minutes days. Such events common many developing economies, where generation delivery infrastructure is often insufficient meet demand operational challenges. Yet, despite large impacts, poor data availability has meant that relatively little known about spatial temporal patterns of electric reliability. Here, we explore expressions instability recorded...
A methodology had been proposed for cross-matching visible infrared imaging radiometer suite (VIIRS) boat detections (VBD) with vessel monitoring system (VMS) tracks. The process involves predicting the probable location of VMS vessels at time each VIIRS data collection an orbital model. Thirty-two months Indonesian was segmented into fishing and transit activity types then cross-matched VBD record. If a record is found within 700 m 5 s predicted location, it marked as match. indicates that...
Data collected by the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) sensors have been archived and processed Earth Observation Group (EOG) at National Oceanic Atmospheric Administration (NOAA) to make global maps of nighttime images since 1994. Over years, EOG has developed automatic algorithms Stable Lights composites from OLS visible band data removing transient lights fires fishing boats. The ephemeral are removed based on their high brightness short...
Fishery closures are widely used to promote the sustainability of fish stocks. agencies typically have very little data relevant planning closure enforcement actions and evaluating effectiveness closures, due in part vast expanse remote nature many closures. In some cases can be evaluated using from GPS based beacons, such as Automatic Identification System (AIS) or Vessel Monitoring Systems (VMS) installed on fishing boats. fisheries where few boats equipped with AIS VMS, rating relies...
