Increases in Global and East Asian Nitrogen Trifluoride (NF₃) Emissions Inferred from Atmospheric Observations.

ABSTRACT: Nitrogen trifluoride (NF₃) is a potent and long-lived greenhouse gas that is widely used in the manufacture of semiconductors, photovoltaic cells, and flat panel displays. Using atmospheric observations from eight monitoring stations from the Advanced Global Atmospheric Gases Experiment (AGAGE) and inverse modeling with a global 3-D atmospheric chemical transport model (GEOS-Chem), we quantify global and regional NF₃ emission from 2015 to 2021. We find that global emissions have grown from 1.93 ± 0.58 Gg yr^-1 (± one standard deviation) in 2015 to 3.38 ± 0.61 Gg yr^-1 in 2021, with an average annual increase of 10% yr^-1. The available observations allow us to attribute significant emissions to China (0.93 ± 0.15 Gg yr^-1 in 201
