OpenAQ Sri Lanka PM2.5

Overview

OpenAQ PM2.5 observations for Colombo and other Sri Lanka locations where public sensors are available.

Methodology

Lankawa queries OpenAQ v3 locations and latest PM2.5 readings for Sri Lanka when an OpenAQ API key is configured. Districts with live matches are overlaid on the seed AQI map; unmatched districts retain seed values with mixed-coverage provenance. When OpenAQ misses Colombo, Open-Meteo air-quality (us_aqi / PM2.5) fills that district.
