• Resumen

  • Two shrinkage events of particles identified in a urban background station of Madrid are discussed in this work. The first occurs during the growth phase of the newly formed particles and the second in the absence of a prior nucleation. These events have been identified in the summer period, towards the end of the day. An increase of the wind speed triggers the displacement of semivolatile species from the particle phase to gas phase producing a shrinkage. The estimated particle shrinkage rates were 6.7 and 4.7 nm·h-1 respectively, for each process identified.
