Sentinel-5P NO₂ in Python: mapping air pollution from TROPOMI over the UK and north-west Europe
Map nitrogen dioxide air pollution from Sentinel-5P TROPOMI Level-2 data in Python: stream a full year of orbits from the Planetary Computer, apply the qa_value > 0.75 filter, grid swaths to a regular raster, build monthly and seasonal composites, rank cities and measure the weekend drop, with an honest explanation of what a tropospheric column is.
