Abstract:
This study investigates the magnitudes and temporal trends of sources and sinks of tropospheric carbonyl sulfide (COS) and their relationship to understanding the atmospheric lifetime as well as other important atmospheric species including carbon dioxide, carbon disulfide, dimethyl sulfide, and biogenic volatile organic compounds. Our analysis incorporates data that was overlooked in previous budgets, recent advances in the understanding of budget components, and temporal data relevant to estimating recent and long-term changes in budget components. While the uncertainty estimates are large and include a missing source that may be the largest individual source, atmospheric inverse studies can constrain these budgets while also addressing critical knowledge gaps for related species, particularly CO2.
