| Zusammenfassung |
| The Maritime Aerosol Network (MAN) has been collecting
data over the oceans since November 2006. The MAN archive provides a
valuable resource for aerosol studies in maritime environments. In the
current paper we investigate correlations between ship-borne aerosol optical
depth (AOD) and near-surface wind speed, either measured (onboard or from
satellite) or modeled (NCEP). According to our analysis, wind speed
influences columnar aerosol optical depth, although the slope of the linear
regression between AOD and wind speed is not steep (~0.004–0.005),
even for strong winds over 10 m s−1. The relationships show significant
scatter (correlation coefficients typically in the range 0.3–0.5); the
majority of this scatter can be explained by the uncertainty on the input
data. The various wind speed sources considered yield similar patterns.
Results are in good agreement with the majority of previously published
relationships between surface wind speed and ship-based or satellite-based
AOD measurements. The basic relationships are similar for all the wind speed
sources considered; however, the gradient of the relationship varies by
around a factor of two depending on the wind data used. |
