During the 35th GAWTEC training session (7th to 20th October 2018) hosted by Umweltforschungsstation Schneefernerhaus (Zugspitze) and the Meteorological Observatory Hohenpeißenberg (DWD) the importance of the MetNO2 project was highlighted to participants, in particular its relevance to the increasing need to monitor the air quality with respect to NOx and the targeted progress beyond the current state of the art. The key points of the course were reactive gases, including NOx/NOy, SO2, surface ozone, carbon monoxide, VOC, which constitute the main focus of the station, and covered measurement techniques and in-lab practicals, data evaluation, data quality assurance and control.

As part of the GAW/WMO capacity building strategy, high data quality objectives (DQO) (based on harmonized measurement techniques, measurement guidelines and standard operating procedures) should be pursued by all participating stations and are of increased importance as many GAW stations in developing countries have become operational. Therefore to achieve comparable and compatible high quality data of atmospheric compositions a network-wide use of only one reference standard is needed. DWD encouraged the participants of other GAW stations to fulfill these standards as well as the importance of calibrating their measurement systems.
