The BEMA-Project. An Overveiw of the Castelporziano Experiments.

This paper reviwes the major outcomes of the measuring campaigns performed at tha Castelporziano nature preserve near Rome, Italy, by 14 European laboratories as part of the BEMA(Biogenic Emission in the Mediterranean Area)-project. Six campaigns of 1-4 weeks duration were carried out in different seasons of the years 1993-1994 at semi-continously running test plots in the nature reserve, representing common Mediterranean vegetation types. The aim was to characterise, at the different test plots, the atmospheric chemical and metereological situations, the plant biomass and physiology, the type, amount and controls of emissions from different plants by means of branch enclosures, and the BVOC emission fluxes from different ecosystems, by scaling up enclosures data from individual sources, and by measuring fluxes directlyby use of micrometereological methods. An important focus during the initial phase of the 5 years BEMA-project was the harmonisation and improvement of the analytical, physiological and micrometereological methods used,and the development and testing of new methods for measuring BVOC fluxes.
