Table 1. Data for the aerosol samples collected following the three dye releases.
Distance inland is the distance from the air sampling location to the nearest point along the shoreline. Distance downwind is the mean distance along the wind vector from the center of the 200 m × 100 m ocean source window to the aerosol sampling site. Distance inland is fixed, whereas distance downwind is subject to the relevant wind directions. [dye]air (pg/m3) is the concentration of dye in the air calculated from the fluorescence intensity and the volume of air sampled. The four samples which match our criteria for dye detection are highlighted in bold. The values for the samples that did not meet our criteria for dye detection are provided in parentheses. [dye]sea (ppb) indicates the sea surface dye concentration measured by the hyperspectral camera and are available for most daylight hours on the day of each dye release and the following day and are not available for aerosol samples collected at night.
