Challenge
Where in Barcelona is NO₂ pollution worst around schools, which micro-environments drive it, and how many measurement points breach air-quality limits?
- Where to start
- Load /srv/data/xaire-no2-barcelona/xaire_datainbrief.csv with pd.read_csv(path, sep=';', encoding='latin-1'). Use the no2_2017 column (bias-corrected, annualised µg/m³) as your headline value and compare against the EU limit (40 µg/m³) and WHO 2021 guideline (10 µg/m³). Break it down by the `type` column (traffic/background/playground/classroom), map the points with lat/long, and rank by `school` (district is in parentheses in the name; drop the campaign-wide 'xAire' label).
- What to share
- An offline map of NO₂ hotspots plus a chart showing NO₂ by micro-environment or by school, and a short paragraph on the traffic pattern near schools and what fraction of tubes exceed the EU limit.
