abstract = {The climate active trace-gas carbonyl sulfide (OCS) is the
most abundant sulfur gas in the atmosphere. A missing source
in its atmospheric budget is currently suggested, resulting
from an upward revision of the vegetation sink. Tropical
oceanic emissions have been proposed to close the resulting
gap in the atmospheric budget. We present a bottom-up
approach including (i) new observations of OCS in surface
waters of the tropical Atlantic, Pacific and Indian oceans
and (ii) a further improved global box model to show that
direct OCS emissions are unlikely to account for the missing
source. The box model suggests an undersaturation of the
surface water with respect to OCS integrated over the entire
tropical ocean area and, further, global annual direct
emissions of OCS well below that suggested by top-down
estimates. In addition, we discuss the potential of indirect
emission from CS2 and dimethylsulfide (DMS) to account for
the gap in the atmospheric budget. This bottom-up estimate
of oceanic emissions has implications for using OCS as a
proxy for global terrestrial CO2 uptake, which is currently
impeded by the inadequate quantification of atmospheric OCS
sources and sinks.},
