Intercomparison of ice nucleating particle (INP) instruments

The ambient cloud in situ measurement campaign is a cross-comparison of cloud in situ measurement instruments with respect to the variables liquid water content and droplet effective diameter. The campaigns focus on the measurement instruments recommended in ACTRIS, such as the PVM. The campaign is organized every two years, with a measurement phase of 3-5 days at Mt. Hohen Sonnblick.

Trainees are introduced to the operation of the specific instrument (PVM). Topics are: Installation, operation, maintenance, data processing, access to ACTRIS data, etc. The training is for staff of cloud in situ NFs, but also for students and young scientists. The aim is to communicate the handling of the instrument according to the ACTRIS criteria.

Transfer of the necessary expertise to operators of an ACTRIS labeled NF and external users (businesses, researchers, monitoring agencies, etc.) to improve their competencies for conducting measurements, data acquisition, data evaluation, and QA/QC measures while covering up to date guidelines and SOPs for anthropogenic NMHCS, biogenic NMHCs, OVOCs, condensables, and NOx. The consultancy shall be

CiGas develops measurement Guidelines (MGs) and Standard Operating Procedures (SOPs) for biogenic NMHCs, OVOCs and condensable vapours and updates the existing ones for anthropogenic NMHCs and NOx), based on proven procedures and methodologies in close cooperation with international bodies (e.g. Global Atmosphere Watch (GAW), National Metrological Institutes (NMIs), AQUILA, EMEP, CEN, ISO), NFs, a

CiGas provides support to the NFs and users for achieving traceability of measurements, quality assurance and quality control of the measurements and the data before submission to public databases. Therefore, data quality and compatibility of ACTRIS trace gas measurements as defined in the MG are ensured by station performance tests as parallel offline measurements, side-by-side intercomparisons,

CiGas is involved in improving, testing and developing new instrumentation for assessing the ACTRIS chemical target variables in air. Specifically, the suitability of new instruments for long-term monitoring within ACTRIS and the conformity with the data quality objectives is tested and characterized.

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

Technological services related to cloud and fog properties. Provision of network-wide accurate calibration of the instruments installed in ACTRIS NFs following harmonized protocols and tools to put all measurements on a common absolute scale. The calibration service could be provided at the TC facility or at NFs, depending on the feasibility. It offers low-uncertainty reference calibration accordi
