Description

Mobile air quality mapping has been performed for black carbon (BC), ultrafine particles (UFP) and particulate matter (PM2.5) to assess the spatial pollutant variability in Warsaw, evaluate source impacts and improve commuter exposure assessment. The measurement set-up is based on the mobile monitoring approaches developed within RI-URBANS. Voluntary participants performed bicycle measurements with portable equipment along a dedicated sampling route during morning (8-9h) and evening (17-18h) rush hours. The monitoring campaigns were performed during the warm (40 runs between September 6th-October 9th, 2024) and cold (42 runs between January 22nd - March 5th, 2025) season.

Prior to the mobile campaigns, the portable instruments (Aethlabs AE51, Naneos Partector 2.0, OpenSeneca) were co-located with high-end instruments at the WOS site for UFP and BC and the local AQMS for PM. GPS localization was provided by a Garmin Forerunner 55 watch.

This dataset includes the raw high-resolution (1-second) data of the portable instruments collected during the mobile monitoring campaigns and merged to seasonal (summer/winter) datafiles based on datetime stamps. This data is currently further processed to construct high-resolution concentration maps as described in the RI-URBANS service tool for urban mapping (ST13).
