Measurement campaign maps GHG emissions and air pollution in Rotterdam

News - 22 August 2022

Scientists from TU Delft, together with scientists from other research institutions, will investigate how the reduction of urban greenhouse gas emissions and air pollution can best be monitored with atmospheric measurements. Monday, August 22, the measurement campaign will start in the Rotterdam region. TU Delft is using mobile radar equipment to measure urban emissions.

The campaign will take place in the period from August 22 to September 9 as a part of the Ruisdael Observatory. Emissions of greenhouse gases and air pollution are estimated based on calculations and emissions reported by companies. In addition, air quality is monitored by the national air quality monitoring network. That network is not designed for determining emissions. Additional atmospheric measurements are therefore required to determine urban emissions. To be sure that planned emission reductions are actually achieved – and not just on paper – it is important to be able to test the calculations with independent measurements. This period of the year is interesting because many activities start again after the relatively quiet holiday period, which hopefully can be seen in the measurements.

A new spatial image
The city of Rotterdam and the Port of Rotterdam are important sources of greenhouse gases and air pollution. In addition to additional measuring instruments at the fixed measuring stations in the region, measuring cars, bicycles equipped with measuring equipment, a measuring trailer and two measuring aircrafts will also be used during the campaign to map the sources. Even from space, satellite instruments will be watching, such as the Dutch TROPOMI instrument that focuses on air pollution and the NASA OCO-3 instrument for measuring carbon dioxide. The measurements are used to improve detailed models of urban greenhouse gas emissions and air pollution.

Ruisdael Observatory
The Ruisdael Observatory is a scientific consortium set up to facilitate reseach on weather and climate topics. It is a partnership made up of a wide range of parties, which enables it to combine all specialisations necessary. The consortium comprises researchers from the Royal Netherlands Meteorological Institute (KNMI), National Institute for Public Health and the Environment (RIVM), Utrecht University, the University of Groningen, VU Amsterdam, Wageningen University & Research, TNO and TU Delft (coordinating university).

Other European Cities
The Ruisdael campaign in Rotterdam does not stand alone, but is part of the European projects RI-Urbans and ICOS Cities. Similar studies will also be conducted in other European cities, including Paris, Bucharest and Milan this summer and autumn.
