Abstrakt: Unlike other pollutants, aerosols, especially the absorbing aerosols, consisting mainly of “black carbon” (BC), interact strongly with the planetary boundary layer (PBL). This study determines the impact of the evolution of PBL and long-range transport on equivalent BC (eBC) concertation under different metrological conditions such as clear sky, foggy (visibility ≤ 1km), and hazy day (visibility ≤ 5 km during the non-fog day), high relative humidity and temperature, also, diurnal and seasonal variability was evaluated. The mean eBC concentration was found to be the lowest during summer, followed by autumn and spring, and the highest in winter for the year 2020. In contrast, the average PBL height was the lowest in autumn, followed by summer and winter, and the highest in spring. The resulting behavior was due to the higher number of rainy days during the summer.
