Hello all,

CPCB (Central Pollution Control Board) has an AQI Repository website with a bunch of Excel files containing hourly, station-level AQI data. I have consolidated the data from these Excel files in a dataset that can be found here: https://github.com/Vonter/india-cpcb-aqi

The dataset contains hourly AQI measurements for about 550 stations spread around the country. The full data dictionary is available here: https://github.com/Vonter/india-cpcb-aqi/blob/main/DATA.md

To quickly explore the data: https://hyparam.github.io/demos/hyparquet/?key=https%3A%2F%2Fraw.githubusercontent.com%2FVonter%2Findia-cpcb-aqi%2Fmain%2Fdata%2Fcpcb-aqi.parquet

To download the full dataset: https://github.com/Vonter/india-cpcb-aqi/raw/refs/heads/main/data/cpcb-aqi.csv.gz

Regards,
