Abstract

Sulfate Formation Mechanisms Derived from Particle Size Distribution Measurements in a Forest in Central Spain A contribution to subproject BIATEX-2 ML Sanchez andR. Rodriguez Dept. of Applied Physics. University of Valladolid. Spain Introduction Gas-to-particle conversion processes are considered one of the main inputs of particles in the atmosphere. As particles are formed they grow and deposit over surfaces contributing to damage in natural ecosystems. Despite the progress achieved in gas-phase chemistry processes over the last decade (Borrell et al, 1997), knowledge of atmospheric chemistry and dominant mechanisms involving aerosol formation is still limited. Information about aerosol formation and growth rates has quite often been derived from particle size distribution measured in smog chamber simulations (Wang et al., 1992). However, the application of this procedure to interpret expe
