A potent greenhouse gas identified in the atmosphere: SF5CF3
We detected a compound previously unreported in the atmosphere, trifluoromethyl sulfur pentafluoride (SF5CF3). Measurements of its infrared absorption cross section show SF5CF3 to have a radiative forcing of 0.57 watt per square meter per parts per billion. This is the largest radiative forcing, on...
