Short summary
Human activities release mercury into the air, but current estimates of these emissions vary widely. Our study examines how the uncertainty in global anthropogenic mercury emission estimates impacts the model's ability to reproduce observations. We found that differences in emissions inventories significantly change results, especially in Asia. The work highlights where increased monitoring is needed to improve estimates and better inform global mercury reduction policies.
