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, as well as all basics in technical issues, such as installation and maintenance of the instruments.

Research and technological services related to cloud and fog properties.

The CCRES is offering development and delivery of tested and traceable procedures for specific calibration of DCRs and MWRs,  possibly including multiple techniques: absolute calibration based on calibrated targets, relative calibration using calibration transfer from a reference instrument, absolute calibration using geophysical targets with known characteristics...

Site performance tests with reference device serve for regular on-site instrument performance check. The TC reference instruments is shipped to NF and measures according to corresponding SOP parallel to the instrument(s) being checked.

Measurement, Data, and Technological services related to cloud and fog properties.

Data evaluation procedures and plausibility tests developed to evaluate the quality of geophysical parameter retrievals and qualify data before it enters the ACTRIS database. Doppler cloud radar and microwave radiometer data should be sent by NFs to the ACTRIS  Cloud Remote Sensing Data Centre. The DC should then be responsible for processing data to produce retrievals of relevant Cloud geophysical properties. Data evaluation, based on various tests should then be implemented to qualify the retrieved data. Methods to test retrieved are established by the TC (e.g. evaluating plausible range, internal consistency,  multi-instrument intercomparisons, …) and data evaluation procedures is developed and provided to the DC for implementation. This software is developed as open-access software.

Calibration of the instruments according to ACTRIS and TC recommendations

QA/QC according to ACTRIS reccommendations and operation guidelines

Organization of training events of operators and scientists to fulfill different requirements: calibration procedures or techniques, training of new operators, support for implementing standard operating procedures, data quality control procedures. It will have a limited number (10-20) of participants and will be organized at the different CCRES units depending on the topics. NF operators are encouraged to participate regularly (once every 2 years). External users are likely to come from national weather services, possibly in the framework of the European E-PROFILE program for MWRs and DLs, and operators involved in airport traffic safety. Training is provided in the form of physical access and virtual-access training is also envisaged.

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.

Following the development of the field (research organizations, private companies) and evaluates the new techniques, whether they could i) replace some of the existing technologies that are used to measure ACTRIS in-situ aerosol variables, ii) improve the capacity of aerosol in-situ observations, iii) be technologically developed enough for network scale operation.

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.

ACTRIS variable-specific analysis tools will be developed and updated to monitor the instrumentation performance at NFs and will facilitate the development of near-real-time data products.
