Cover Story: Analysis of long-term particle number size distribution (diameter 0.01–10 µm) measurement in Amman revealed that aerosol concentrations have clear diurnal, weekly, and seasonal characteristics of high concentrations during traffic rush hours, workdays, and winter. The daily mean submicron particle number concentration was 6.5 × 103–7.7 × 104 cm−3. Ultrafine particles (Dp < 0.1 µm) were 93% of the submicron particles. The modal structure was characterized by five modes (Dpg,I, Ni): nucleation (22 nm, 9.4 × 103 cm−3), Aitken (62 nm, 3.9 × 103 cm−3), accumulation (225 nm, 158 cm−3), coarse (2.23 µm, 1.2 cm−3), and a new particle formation (NPF) mode with a geometric mean diameter of <10 nm. The wind speed and temperature had major impacts on the concentrations. View this paper.
