China-EU remote emission sensing research exchange meeting
December 10, 2022
In August, the first exchange meeting following the pandemic between CARES and the Chinese remote emission sensing research teams was organized. Since the previous meeting in March 2021, substantial progress has been made in the field in both EU and China.
In the Chinese MOST project, this summer a city demonstration campaign was carried out in the city of Tangshan in the Hebei province. The city has many industries, a large port and serves as the main traffic corridor to north-eastern China, therefore a lot of heavy-duty trucks could be measured with the Chinese multi-lanes vertical commercial remote sensor and a newly developed point sampling instrument. Demonstration measurements will also be carried out this winter in the city of Chengdu in the Sichuan province in southwestern China.
The CARES partner Hong Kong University of Science & Technology has developed a small high speed sensor for point sampling measurements of NO, NO2, CO and CO2 emissions. The sensor has been successfully deployed sensor networks in both busy street canyons and along open roads in Hong Kong to assess traffic-related air pollution and proven to have a huge potential for policy making and exposure estimations in one go.
