AB: This study presents particles size distributions with the diameter from 4 to 2000 nm measured during the CRYSTAL-FACE mission on July 2002 in Florida. Particle sizes were characterized with the FCAS (90-2000 nm) and NMASS (4-100 nm) aboard the WB-57F. During several intense cloud processing events, high concentrations ($>$100 particles per cc) of particles with the diameter smaller than 10 nm were observed. Particle size distributions during biomass burning and Saharan dust storm events are also discussed with case studies. These observations are further compared with our previous tropical measurements from WAM (1998) and ACCENT (1999).
