Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>We report in situ atmospheric measurements of hydrofluorocarbon HFC‐43‐10mee (C₅H₂F₁₀; 1, 1, 1, 2, 2, 3, 4, 5, 5, 5‐decafluoropentane) from seven observatories at various latitudes, together with measurements of archived air samples and recent Antarctic flask air samples. The global mean tropospheric abundance was 0.21 ± 0.05 ppt (parts per trillion, dry air mole fraction) in 2012, rising from 0.04 ± 0.03 ppt in 2000. We combine the measurements with a model and an inverse method to estimate rising global emissions—from 0.43 ± 0.34 Gg yr⁻¹ in 2000 to 1.13 ± 0.31 Gg yr⁻¹ in 2012 (~1.9 Tg CO₂‐eq yr⁻¹ based on a 100 year global warming potential of 1660). HFC‐43‐10mee—a cleaning solvent used in the electronics industry—is currently a minor contributor to global radiative forcing relative to total HFCs; however, our calculated emissions highlight a significant difference from the available reported figures and projected estimates.</p> </abstract>
