This paper has its origin via an inadvertent error wherein a length of rubber hose was added to the sampling line of a sulphur gas analyser at the Australian Baseline Station at Cape Grim. This carbon disulphide (CS₂) contamination source was removed after a period of 10 weeks. In the interim, substantial data was collected and is here compared with the record of ambient station temperatures. CS₂ was found to vary with ambient temperature over both short and monthly time scales. Comparisons of linear, natural log (ln) and log₁₀ correlations yield the conclusion that log₁₀ and ln CS₂ emission vs. temperature (°C) associations provide the best correlations. No significant depletion of CS₂ emission from the rubber over a 10-week period was detected. Implications for regional and global emission inventories of CS₂ and carbonylsulphide (COS) are discussed.
