Cluster Calibration Centre (CCC), University of Helsinki (part of CAIS-ECAC) organizes the next NAIS intercomparison and training workshops in autumn 2024 and spring 2025 in Helsinki

Cluster Calibration Centre (CCC) organizes the next two Intercomparison workshops for ion spectrometers (NAIS) in autumn 2024 (18-29.11.2024) and spring 2025 (31.3-11.4.2025) in Helsinki, Finland. CCC has invited to the workshops the ACTRIS NFs - performing NAIS measurements - that have received the ACTRIS initial label (in aerosol in situ measurements) or that are expected to receive the initial label soon. Other interested parties can contact CCC (actris-ccc@helsinki.fi) to see if there is room left in the workshops.

The workshops are part of the operation support activities CCC provides to ACTRIS National Facilities (NFs) that perform sub-10 nm particle measurements as part of Centre for Aerosol In Situ Measurements – European Center for Aerosol Calibration and Characterization (CAIS-ECAC). NAIS intercomparison and training workshops are organized regularly.
