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...
