AB - <jats:p>Sea surface images obtained during the 2006 Marine Aerosol Production (MAP) campaign in the North East Atlantic were analysed for values of percentage whitecap coverage (<jats:italic>W</jats:italic>). Values of <jats:italic>W</jats:italic> are presented for wind speeds up to <jats:italic>circa</jats:italic> 23 m s<jats:sup>−1</jats:sup>. The <jats:italic>W</jats:italic> data were divided into two overlapping groups and a piecewise, windspeedonly parameterization of <jats:italic>W</jats:italic> is proposed that is valid for wind speeds between 3.70 m s<jats:sup>−1</jats:sup> and 23.09 m s<jats:sup>−1</jats:sup>. Segregation of data points based upon a 2.5 hour wind history acted to decrease data scatter at wind speeds above approximately 9.25 m s<jats:sup>−1</jats:sup>. At these wind speeds <jats:italic>W</jats:italic> values were greater for decreasing wind speeds than for increasing wind speeds. No clear wind history effect was observed at wind speeds below 9.25 m s<jats:sup>−1</jats:sup>.</jats:p>
