WP4 - Investigation of the connections and correlations, between the meteorological parameters and the pollution levels with PM2.5, black carbon (BC) and PAHs for urban conditions in Bulgaria.

   Activities under WP4:

  1. 4.1. Distinguishing of the significant meteorological parameters related to PM pollution levels.
  2. 4.2. Calculation of the Probabilistic Contribution Probability Function (CPF) depending on the prevailing wind direction and speed.
  3. 4.3. Application of a trajectory model to identify the origin and transport of air masses in selected cases of concentration deviations of the elements.
