A Fifteen Year Record of Global Natural Gas Flaring Derived from Satellite Data

open access: yesEnergies, 2009
We have produced annual estimates of national and global gas flaring and gas flaring efficiency from 1994 through 2008 using low light imaging data acquired by the Defense Meteorological Satellite Program (DMSP). Gas flaring is a widely used practice for
