• round robin VOC + monoterpenes + side-by-side NOx – stations got feed-back and questions - waiting for station answers• learn about superior techniques, problematic techniques – input for Measurement Guidelines and QA, distribute in community, improve• upcoming OVOC intercomparison with GC-MS/FID and PTR-MS instruments at Hohenpeissenberg in October• papers on RR and comparisons-results• next version Draft Measurement Guidelines – ACTRIS + GAW community – Cross-link with IAGOS, PEGASOS, iLeaps, AQUILA - finalize in GAW Reports• station audits• EBAS data reporting feed-back (data evaluations)
