An Improved Calibration for Satellite Estimation of Flared Gas Volumes from VIIRS Nighttime Data

Payne Institute Earth Observation Group Mikhail Zhizhin, Christopher D. Elvidge, Tamara Sparks, Tilottama Ghosh, Morgan Bazilian and Feng-Chi Hsu write about how the VIIRS Nightfire (VNF) data product is particularly useful for monitoring of global natural gas flaring and estimation of flared gas volumes. In this paper we report on the development of an empirical calibration for estimating flared gas volumes based on VIIRS observations of flares running at low, medium, and high flared gas volumes. Tests were run with both single and double flares, with and without atmospheric correction.  September 8, 2025.
