EMEP laboratory intercomparison


EMEP has arranged laboratory intercomparisons on an almost annual basis since 1977, and currently 40 rounds have been arranged. All EMEP laboratories are obligated to participate, and the comparison is also open to other laboratories in relevant programmes. Since round 29, results are published here and certificates are mailed to the participationg laboratories. Earlier results are published in data reports.

EMEP intercomparison results are used to calculate QA measures.
