A Potent Greenhouse Gas Identified in the Atmosphere: SF 5 CF 3
We detected a compound previously unreported in the atmosphere, trifluoromethyl sulfur pentafluoride (SF 5 CF 3 ). Measurements of its infrared absorption cross section show SF 5 CF 3 to have a radiative forcing of 0.57 watt per square meter per parts per billion. This is the largest radiative forci...
