Gary M. Lovett 1994 set the constant median dry deposition velocity of PM10 at about 0.0064 m/s in the equation; PM10 deposition = Vd.Ci.Ti. 24.3600. How to determine the constant average value of the dry deposition velocity of PM10 and PM2.5 from literature? Is the same constant value of the dry deposition velocity of PM10 can be used for different cities or need to change depending on climatic factors? And what is the constant dry deposition velocity value of PM2.5 ?
Hello,
You will not be able to define an average deposition rate of PM10 or PM2.5 without knowing the composition of this range of aerosol. Indeed the deposition speed is linked to the size but also to the density of the particles. The difficulty in the fraction PM10 or PM2,5 is that you have potentially completely different particles in size going from 0,3 to 10 µm for PM10 for example and completely different compositions thus different densities.
Kind regards,
