Fetching and Visualizing Daily Air Quality Data

Submitted Apr 14, 2025

Description

Often publicly available datasets from Indian government agencies/bodies are available in the form of PDF tables (in fact, sometimes scanned PDF tables). One such dataset includes the daily air quality data that is published by the Central Pollution Control Board at 4:00PM everyday. I created an automated Python script to scrape through these tables every day at 4:30PM. Subsequently I automated a Julia script to visualize daily air quality data (index, level, and major pollutant). And finally, using Git I publish these plots daily at 5:30PM on my blog. This is an effort to make government sourced data more accessible and available.
