Air quality partners met for a site visit in Turku

In June, partner representatives from the city of Turku, the Finnish Meteorological Institute (FMI) and the University of Turku gathered for a site visit in the Student Village, Turku’s Positive Energy District (PED). The purpose of the site visit was for the partners involved in air quality activities, to get familiar with the PED air quality characteristics and the overall air quality measures and monitoring in Turku. In RESPONSE, FMI is responsible for meteorological and dispersion modelling activities. FMI will for example develop SILAM Air Quality Modelling for the PED and demonstrate the use of a high-resolution operative air quality forecasting system. The University of Turku, more specifically the department of Geography and Geology, is providing high-resolution local climate information with a focus on urban planning.

During the visit, air quality expert Petra Sainisto from the city of Turku introduced the subject of air quality in Turku, stating that there are quite few days per year with poor air quality in the city. When the air quality level drops, it usually happens in spring when the streets dry and the level of dust particles in the air increases.

The tour around the Student Village started on the Aitiopaikka building rooftop which provided a good overview of the PED area. Aitiopaikka, built in 2018 is a four-story apartment building equipped with 516 solar panels. After seeing the PED from above, the site visit led by environmental expert Hans-Peter Huhtala from the city of Turku, continued on the ground. The University of Turku has several air quality measuring sensors in the PED area which are part of the TURCLIM urban weather observation network. The site visit was completed with a stop at the Turku market square air quality measuring station, which monitors the traffic’s impact on the city centre air quality.
