Abstract

The ParisFog field experiment conducted at the Site Instrumental de Recherche en Télédétection Atmosphérique (SIRTA) observatory has been reported. The experiment aimed at monitoring simultaneously thermodynamic, dynamic and turbulent microphysical and radiative processes, and chemical composition of aerosols in low-visibility situations occurring in a large range of a large range of synoptic conditions. Several systems were deployed to study the aerosol particle properties present during the fog life cycle including an aethalometer and a nephelometer to characterize absorption and scattering properties of particles, respectively. It included several particle size counters to cover the nano- to micrometer particle size range. The analysis showed the aerosol number concentration (Naer), measured by a condensation particle counter (CPC), ranged from 1,000 to 30,000 cm -3 during ParisFog.
