Abstract

SO2 and O2 deposition fluxes over Madrid area: results of one year deposition field experiment R. San Jose, J. Moreno, J. Cortes Group of Environmental Software and Modelling, Computer Science School, Technical University of Madrid, Campus de Montegancedo, Boadilla del Monte 28660, Madrid, Spain Abstract Dry deposition flux of trace gases is often parameterized in models as the con- centration of the trace gas at a specific height multiplied by a deposition velocity (Vd) which depends on atmospheric parameters as well as specific surface param- eters. The parameterization of the deposition velocity is usually expressed in terms of aerodynamic resistance, which is a function of the physical state of the atmosphere and a surface resistance, which is a function of the chemical, physical and biological properties of the surface. The parameterization of these resistances is under discussion and field experiments are essential for this objective. A field experiment during one year has been
