Measurement guidelines for NFs for instruments dealing with aerosol physical properties (for observational and exploratory platforms)

Scientific exploration at outdoor chambers for the study of atmospheric behavior of biogenic and anthropogenic VOCs, formation of products including ozone and aerosols under near-real conditions (use of natural light & high volume: 200m3) and their impact on the air quality. The chambers are equipped with a wide variety of instruments, also state-of-the-art systems, for that purpose. Intercomparison of instrumentation with the possibility of accommodating a large number of external instruments can be carried out. The facilities are suitable for testing, developing or improving new instruments to measure compounds in the air, testing innovative depolluting solutions relevant to air quality management, etc. In this sense, the facilities can be adapted to specific user’s demands so that researchers and industry can test their research-grade and close-to-market initiatives at nearly-real controlled conditions, which will help them to characterize and enhance their prototypes and technologies, models or research items.
Training stays, bottom-up oriented, within a research topic framework guided by expert staff are welcome.

1) Calibration of photometer, QA QC support, evaluation of site performances, Traceability, duty cycle increase, development of new instrument and procedure, development of new algorithms, support to campaigns, training

2) Quality assured data, access to all AERONET and ACTRIS data

The access to the centralized processing system allows the users to retrieve aerosol optical properties profiles using the same processing chain implemented within ACTRIS.

This activity disseminates the knowledge of the CAIS/ECAC to the stakeholders. The knowledge transfer includes education and training activities organized by the CAIS/ECAC and different units.

Operators and scientists are trained through courses, workshops and hands-on training sessions. The training enables the operators and scientists to be introduced into the measurement guidelines/SOPs, QA/QC criteria and control, and troubleshooting. Participants are trained in sample preparation, sample analysis and quantification with different instruments. Participants can bring their own samples.

The performance of methods and instruments for measuring the elemental composition of aerosols is evaluated against distributed reference standards.

Provision of up-to-date guidelines for measuring the elemental composition of aerosols.

The performance of NFs measuring elemental composition of particulate matter samples is evaluated based on: QA/QC outputs, participation in inter-laboratory comparisons, calibration and training workshops, and effective data reporting to ACTRIS DC. Service available to external users

Training and capacity-building (possibility to tailor the training depending on the interests of the participants, e.g. usage of high-resolution-DMA calibration setup, operation of PSM or NAIS, sampling of sub-10nm particles)

This service is to calibrate nano-mobility particle size spectrometers, ion spectrometers or nano-CPCs in the size range of ca. 1-10 nm in mobility diameter
