Virtual training on metrology of VOC atmospheric measurements


Training introduction

In the framework of the project MetClimVOC, we organized a virtual training addressing the topics described below.

Atmospheric measurements of volatile organic compounds at monitoring stations (Dr. Rainer Steinbrecher, KIT): the VOC monitoring networks of Global Atmosphere Watch (GAW) and of the upcoming European Research Infrastructure on Aerosol, Clouds and Trace Gases (ACTRIS) were shortly introduced with its key objective of providing high quality data of known uncertainty. Necessary data quality assurance and control processes, as well as the success of the measures in the GAW-VOC network were shown.

Metrological vocabulary and traceability (Bernhard Niederhauser, METAS): during this presentation, metrological terms and concepts, such as measurand, uncertainty, calibration hierarchy and traceability to the international system of units were clarified.

Preparation, traceability and uncertainty of static reference gas mixtures (Annarita Baldan, VSL):in this presentation, the preparation of static reference gas mixtures (RGMs) was described, showing the traceability of the process and the main contributors to the uncertainty of the preparation.

Generation, traceability and uncertainty of dynamic reference gas mixtures (Dr. Maitane Iturrate-Garcia, METAS): the system used to generate dynamic primary RGMs using the permeation method was described, showing the traceability of the generation process and the main contributors to the uncertainty of the generated RGMs. An example of secondary RGMs was briefly shown.
