Central facility

CiGAS-CH provides remote access for the support of users of the @VOC@ tool, used for VOC data quality assessment.

Measurement and calibration for N2O isotopes.

Measurement and calibration for VOCs/halocarbons.

Calibration of photometers in terms of Langley procedures in pristine conditions (a certificate will be provided) and comparison of photometers with reference instrument enabling improvements and optimization of them. 

The service consists of:
·       Quality-assurance of physical and optical in-situ aerosol measurements achieved via instrument intercomparisons, calibration workshops, round-robin test and on-site intercomparisons
·       Capacity building to perform high-quality physical and optical in-situ aerosol characterization via on-site trainings and trainings in the calibration workshops

Estimated duration: There are special time slots for the workshops.
