any wind direction. However, sea-salt transport inland, to the monitoring site,
depends on a specific wind component directed from sea to land. Because of
coarse resolution, the model produced the same sea-salt concentration over the
monitoring site as over the adjacent sea area. This is correct for all sites located
over the land, except for those located at very small islands.
Fig. 1. Comparison between modeled sea-salt concentrations (the black lines) and measurements
(the grey lines) in (a) Finokalia, Crete, (b,c) Barcelona, Spain, and (d) Tel-Aviv, Israel (Adapted
from Kishcha et al. (2009))
The model-vs.-measurement comparison in Barcelona showed that for the
majority of days, the model produced quite realistic sea-salt concentrations (Fig.
1b and c). An average simulated aerosol concentration (±standard deviation) ranged
within the same interval as the measurements did 2 ± 2 μg/m 3 . The relatively high
standard deviation indicates strong variability of sea-salt aerosol concentrations
