Who are we?
AirData.kz is a non-profit open data project launched by enthusiasts from Global Shapers Almaty, an initiative of the World Economic Forum.
Why this matters
Every winter, Almaty disappears under a blanket of smog. PM2.5 levels reach 10 to 20 times above what the WHO considers safe. People breathe this air. Children walk to school in it.
But the data about it is scattered — different networks, different formats, different units, much of it hard to access. We believe that before you can solve a problem, you need to see it clearly. That is what we are trying to do.
What we do
Store historical data
Air quality data disappears quickly — most sources only keep recent readings. We have been operating since 2019, building a record that researchers and journalists can rely on.
Provide public access
We believe air quality data is a public good. Everything we collect is cleaned, documented, and published openly — no accounts, no paywalls, no restrictions.
Raise awareness
When people can see the numbers — the winter spikes, the neighborhoods most affected — it becomes harder to look away. Data makes the invisible visible.
"Liberty is the right not to lie.
Freedom is the right to never have to lie." Albert Camus
We present data in its purest form. We do not alter it, we do not hide it, and we do not choose what to share. Our commitment is simple — honest, open, and dependable information about the air we all breathe.
These words carry a particular weight for us. AirData.kz was created in an environment where sharing data openly was not entirely safe. That time has passed, thankfully — but we keep this quote as a reminder of why we started, and what we believe data should always be: free, honest, and available to everyone.
