Article Synopsis
  • This study examines new particle formation (NPF) events in Rehovot, Israel, during two campaigns, focusing on particle size, composition, and gaseous pollutants.
  • Researchers identified major sources of organic aerosols from hydrocarbons and biomass burning, and observed significant daytime and nighttime NPF events linked to photochemistry and other chemical species.
  • A hybrid positive matrix factorization analysis revealed that various components, like ammonium sulfate and different organic aerosol types, play key roles in both nucleation and particle growth processes during these events.

Number-size distribution is one of the important microphysical properties of atmospheric aerosols that influence aerosol life cycle, aerosol-radiation interaction as well as aerosol-cloud interactions. Making use of one-yearlong measurements of aerosol particle number-size distributions (PNSD) over a broad size spectrum (~15-15,000nm) from a tropical coastal semi-urban location-Trivandrum (Thiruvananthapuram), the size characteristics, their seasonality and response to mesoscale and synoptic scale meteorology are examined. While the accumulation mode contributed mostly to the annual mean concentration, ultrafine particles (having diameter <100nm) contributed as much as 45% to the total concentration, and thus constitute a strong reservoir, that would add to the larger particles through size transformation.
