【 摘 要 】

The SWIR-radiance FRP method is applied to the Along Track Scanning Radiometer series of sensors, and the follow-on Sea and Land Surface Temperature Radiometer (SLSTR) sensor to provide both the longest and the most recent assessment of global gas flaring activity to date. Our inventory covers more than two decades, and demonstrates that total flare site numbers peak in 2008 (similar to 14,000 global 1-arcminute grid cells containing flares) and that since then there has been an overall reduction to mid-2018 (similar to 10,400 cells) When considering radiant heat output (SWIR-radiance derived FRP), a downward global trend identified between 2000 (similar to 15.1 GW) and 2011 (similar to 12.4 GW) has stalled, with a slight increase observed by mid-2018 (similar to 13 GW). We also find through calibration against flared gas quantities derived from the Defence Meteorological Satellite Programme (DMSP) satellites, that 131 billion cubic metres of natural gas has been flared globally between May 2017 and May 2018.
