Paper on 'Positive trends in Southern Hemisphere carbonyl sulfide' by
Stefanie Kremser, Nicholas B. Jones, Mathias Palm, Bernard Lejeune,
Yuting Wang, Dan Smale, and Nicholas M. Deutscher accepted and published
online: http://onlinelibrary.wiley.com/doi/10.1002/2015GL065879/full This paper focuses on the analysis of carbonyl sulfide (OCS)
measurements obtained from ground-based Fourier transform spectrometer
(FTS) instruments at three Southern Hemisphere sites spanning
34.45°S to 77.80°S. At all three sites statistically significant
positive trends are seen from 2001 to 2014 with an observed overall
trend in total column OCS at Wollongong of 0.73 ± 0.03%/yr, at Lauder of
0.43 ± 0.02%/yr, and at Arrival Heights of 0.45± 0.05%/yr. These
observed trends in OCS imply that the OCS budget is not balanced and
therefore provides new constraints on current estimates of sources and
sinks. This research was supported by the Royal Society of
New Zealand through the Marsden Fast-Start Fund. |
