Spada, M., O. Jorba, C. Pérez García-Pando, Z. Janjic, and J.M. Baldasano, 2015: On the evaluation of global sea-salt aerosol models at coastal/orographic stations. Atmos. Environ., 101, 41-48, doi:10.1016/j.atmosenv.2014.11.019.

Sea-salt aerosol global models are typically evaluated with in situ concentration observations at coastal stations that are unaffected by local surf conditions and thus considered representative of open ocean conditions. Despite recent improvements in sea-salt source function, studies still show significant model errors in specific regions. Using a multiscale model, we investigated the effect of increased model resolution (0.1°×0.1° vs. 1°×1.4°) upon sea-salt aerosol patterns in four stations from the University of Miami Network: Baring Head, Chatam Island, and Invercargill in New Zealand, and Marion Island in the sub-antarctic Indian Ocean. Normalized biases were reduced from +63.7% 15 to +3.3% and overall correlation increased from 0.52 to 0.84. The representation of sea/land interfaces, mesoscale circulations, and precipitation with the higher resolution model played a major role in the simulation of annual concentration trends. Our results recommend caution when comparing or constraining sea-salt source functions in global models using surface concentration observations from coastal stations.
