Rich Data Variables: Integration of Ten Years of Daily Weather, Traffic, and Air Pollution Data Across Six Largest Norwegian Cities

This study combines a decade of daily weather, traffic, and air quality data from Norway's six largest cities. The data is sourced from the Norwegian Public Roads Administration, the Norwegian Institute of Air Research, and the Norwegian Meteorological Institute. Careful selection and verification of monitoring stations were conducted to ensure accuracy and consistency. Initially focusing on the top ten populous cities, monitoring sites for traffic and air pollution were scrutinized. Weather variables were then aligned with selected sites, resulting in a dataset spanning 2009 to 2018. It includes key pollutants like NO, NO2, NOx, PM2.5, and PM10. This dataset has significant potential for further analysis and informing policy decisions, making it valuable for researchers and policymakers studying the connections between weather, traffic, and air quality in urban areas.
