Global Gas Flare Survey by Infrared Imaging, VIIRS Nightfire, 2012-2019

This dataset contains annual global flare site surveys from 2012-2019 derived from Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi National Polar Partnership (SNPP) satellite. Gas flaring sites were identified from heat anomalies first estimated by the VIIRS Nightfire (VNF) algorithm from which high-temperature biomass burning and low-temperature gas flaring were separated based on temperature and persistence. Nightly observations for each flare site were drawn to determine their activity in the given calendar year. Data include flare location, temperature, and estimated flared gas volume; flaring data summarized by country; and KMZ files for viewing flaring locations in Google Earth. This dataset is valuable for measuring the current status of global gas flaring, which can have significant environmental impacts.

本数据集汇聚了2012至2019年间全球年度 flare 地点调查数据，该数据源自苏omi国家极地合作计划（SNPP）卫星搭载的可见光红外成像辐射计套件（VIIRS）。通过VIIRS夜火（VNF）算法从热异常中识别出燃气泄漏地点，并根据温度和持续性将高温生物质燃烧与低温燃气泄漏区分开来。针对每个flare地点的夜间观测被用于确定其在指定日历年度内的活动情况。数据包括flare位置、温度和估算的燃气泄漏量；按国家汇总的flare数据；以及用于在谷歌地球中查看燃气泄漏位置的KMZ文件。本数据集对于评估全球燃气泄漏的当前状况具有重要意义，而燃气泄漏可能对环境产生显著影响。
