They can be defined as the removal from the atmosphere of the differ- ent chemical compounds which are deposited over the different surfaces which are found in a complex environment such us urban centers and surroundings. Mesoscale Transport Models use the deposition modules to remove pollutants from the atmosphere and the quality and importance of the deposition parameter- ization processes is out of question. The classical approach of deposition processes into the dispersion models has been based on the so-called "big-leaf' approach which is based on a former version of the resistance technique introduced in
