Short summary
The paper addresses a two-order-of-magnitude discrepancy in deposition velocities of accumulation-mode aerosols measured with different methods. This uncertainty affects current atmospheric deposition models. By explicitly accounting for gas-particle transition and explicitly evaluating the observed quantities we could reproduce the observations . Resolving the discrepancy, reduces uncertainties in simulated concentrations and fallout.
