ESAC I and II: Experimental Studies of Atmospheric Changes, 1st and 2nd phase

Updated 2003-06-25

The main objectives of ESAC II are the following: (1) Extend and improve the important existing Belgian contribution in atmospheric research started in the 50s, recognized internationally. (2) Investigate the chemistry of the atmosphere, to detect and understand its evolution, mainly with experimental means. Special attention will be paid to the evolution of the ozone layer and chemical species and processes with an impact on climate changes. (3) Support the Belgian policies and decisions regarding the Amendments to: - the Montreal Protocol on Substances that deplete the Ozone Layer; - the Kyoto Protocol on Greenhouse Gases (GHG) emissions.

Methods & Procedures

Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc. --> Methodology: (1) Regular monitoring activities (permanent measurements): Long-term surveillance of the atmosphere and related data analysis, validation and interpretation. (2) Campaign observations (3) Extension of observation and data analysis capabilities (4) High-accuracy laboratory spectroscopic measurements in support of atmospheric observations (5) Integration of experimental data with numerical models (6) Valorisation of results
