Transparent exopolymer particles (TEP) and sodium in ambient aerosol particles and cloud water at Cape Verde islands ...
Transparent exopolymer particles (TEP) exhibit the properties of gels and may enter the atmosphere as part of sea spray aerosol. Here, we report number concentrations of TEP (diameter> 4.5 µm) in ambient aerosol (total suspended particles, TSP) and cloud water samples from the tropical Atlantic O...

| Summary: | Transparent exopolymer particles (TEP) exhibit the properties of gels and may enter the atmosphere as part of sea spray aerosol. Here, we report number concentrations of TEP (diameter> 4.5 µm) in ambient aerosol (total suspended particles, TSP) and cloud water samples from the tropical Atlantic Ocean as well as in generated aerosol particles (PM10) using a plunging waterfall tank that was filled with the ambient sea water. Samples were taken during the MarParCloud: “Marine biological production, organic aerosol particles and marine clouds: a Process chain” campaign that took place from September 13th to October 13th 2017 at the Cape Verde archipelago Island Sao Vicente located in the Eastern Tropical North Atlantic (ETNA). Total suspended aerosol particle (TSP) for TEP analysis and PM10 sampling for sodium analysis was performed on top of a 30 m sampling tower of the CVAO. TSP were sampled with a filter sampler consisting of a filter holder equipped with a 0.2 µm pore-sized, acid-cleaned polycarbonate ... |
