OVOCcomp
Oxygenated volatile organic compounds (OVOC) are important players in tropospheric photochemistry. They are emitted from anthropogenic and natural sources but also formed in the photochemical transformation of other VOC.
Within the frame of the integration task on "Quality Assurance/Quality Control (QA/QC)" a workshop was held at the Research Centre Jülich, Germany, October 11-12, 2004, to prepare the intercomparison experiment at the atmosphere simulation chamber SAPHIR. The intercomparison experiment was carried out January 17-28, 2005. 12 groups participated with a variety of different instruments covering the whole range from standard techniques to newly developed methods. The intercomparison was conducted as a "blind" intercomparison. The referee is Eric Apel, NCAR, Boulder, CO, USA.
The results of the ACCENT OVOC intercomparison activity will improve the methods for the measurement of OVOC in the atmosphere, foster analytical training, enhance the transfer of knowledge through scientific and technical communication among the participants, and demonstrate the importance of regular proficiency tests to stay abreast of advancing technology.
