PM10/PM2.5 comparison exercise in Oslo, Norway. Study in 2015-2016 and 2018.

Marsteen, Leif; Hak, Claudia

Formålet med sammenligningen var å ekvivalensteste og etablere kalibreringsfaktorer for de vanligste automatiske PM-målere som er i bruk i Norge. For å etablere faktorene utførte Referanselaboratoriet en feltstudie på tre steder i Oslo under sommer- og vinterforhold i periodene september 2015 til juli 2016 og februar til mars 2018. Måleinstrumentene som deltok var Palas Fidas 200, Grimm EDM 180, TEI TEOM 1405 DF, TEI FH 62 I-R, og R&P TEOM 1400AB.

Rapporten beskriver et mulig system for kontinuerlig verifikasjon av kalibreringsfaktorene i de norske målenettene og hvordan analysedata skal kalibreres.

PM2.5 Retrieval Using Aerosol Optical Depth, Meteorological Variables, and Artificial Intelligence

Logothetis, Stavros-Andreas; Kosmopoulos, Georgios; Salamalikis, Vasileios; Kazantzidis, Andreas

Particulate matter (PM) is one of the major air pollutants that has adverse impacts on human health. The aim of this study is to present an alternative approach for retrieving fine PM (particles with an aerodynamic diameter less than 2.5 μm, PM2.5) using artificial intelligence. Ground-based instruments, including a hand-held Microtops II sun photometer (for aerosol optical depth), a PurpleAir sensor (for PM2.5), and Rotronic sensors (for temperature and relative humidity), are used for the machine learning algorithm training. The retrieved PM2.5 reveals an adequate performance with an error of 0.08 μg m−3 and a Pearson correlation coefficient of 0.84.
