Welcome to the
Center for Aerosol In-Situ - European Center for Aerosol Calibration and Characterization

In the frame of the European Research Infrastructure ACTRIS-ERIC, the European Center for Aerosol Calibration and Characterization (CAIS-ECAC) is one of the Central Facilities for the ACTRIS National Facilities and external users worldwide. CAIS-ECAC’s mission is to offer operational support for quality assured and controlled physical and chemical aerosol in situ measurements & sampling, to conduct traceable instrument calibration, and to perform laboratory analysis of aerosol samples. Furthermore, CAIS-ECAC develops and offers Near-Real-Time tools for fast data submission and central quality control.

CAIS-ECAC is a consortium, consisting of seven facilities. The WCCAP (World Calibration Center for Aerosol Physics), PACC (Prague Aerosol Calibration Center), and CCC (Cluster Calibration Center) are responsible for aerosol microphysical and optical aerosol variables. The OCTAC-CC (Organic Tracer and Aerosol Constituents - Calibration Center), ERLAP (European Reference Laboratory for Air Pollution), the ACMCC (Aerosol Chemical Monitor Calibration Center) and EMC2 (Element Mass Calibration Center) are in charge of the chemical & elemental aerosol variables.



which consists of
Seven Central Facilities



and is responsible for
65 National Facilities in 18 countries.

World Calibration Centre for Aerosol Physics (WCCAP)
The WCCAP was founded in 2002 to serve as a competence center for in-situ physical and optical aerosol measurements as part of the world-wide GAW-program of the WMO. This WCCAP is world-wide unique for the quality assurance of physical and optical in-situ aerosol measurements and station audits to improve infrastructures.
