| Zusammenfassung |
| Most estimates of sea spray aerosol source functions have used indirect
means to infer the rate of production as a function of wind speed. Only
recently has the technology become available to make high frequency
measurements of aerosol spectra suitable for direct eddy correlation
determination of the sea spray particle flux. This was accomplished in this
study by combining a newly developed fast aerosol particle counter with an
ultrasonic anemometer which allowed for eddy covariance measurements of
size-segregated particle fluxes. The aerosol instrument is the Compact
Lightweight Aerosol Spectrometer Probe (CLASP) – capable of measuring
8-channel size spectra for mean radii between 0.15 and 3.5 µm at 10 Hz.
The first successful measurements were made during the Waves, Air Sea
Fluxes, Aerosol and Bubbles (WASFAB) field campaign in October 2005 in Duck
(NC, USA). The method and initial results are presented and comparisons are
made with recent sea spray source functions from the literature. |
