We will be looking at NO2 concentrations over metropolitan statistical areas (MSA) or combined statistical areas (CBSA) as defined by the US census bureau, details here here.
These are sets of core and outlying counties that should be considered together as part of a central metropolitan area.
The shapefiles are available here (search on the page for "Metropolitan and Micropolitan Statistical Areas and Related Statistical Areas"). Select the latest dataset (currently 2023)
This issue involves importing the shape files into google earth engine, extracting the geometries for each CBSA and transforming it to a featureCollection.
