What Atmos does

Everything in the air where you are,
explained rather than averaged.

Atmos measures the air where you are and keeps every detail: each pollutant, each pollen species, each nearby fire. Then it tells you plainly which of it matters today, and what to do about it.

Pollen

Pollen is a fine, powdery substance that trees, grasses and flowers release as part of how they reproduce. Wind and insects carry it from one plant to another. For most of us it is invisible background noise. For many people it is the reason spring and summer bring sneezing, itchy eyes and congestion, as the immune system mistakes these tiny particles for a threat.

  • Grass, birch, alder, ragweed, mugwort and olive, tracked separately
  • Peaks as well as current levels, because ragweed peaks mid-morning and mugwort at night
  • Three days ahead, so you can see which day is the bad one

Wildfire

See the fire, and the smoke it sends

Satellites spot active fires twice a day. Atmos plots them around you and watches what the smoke does to the air you are actually breathing.

  • Live fire detections from NASA FIRMS satellites
  • Alerts when smoke pushes PM2.5 up near you, not just when a fire is close
  • Distance and intensity for every detection on the map

Air quality

The number, and what is behind it

An air quality index is a national judgement rather than a measurement, so the same air is labelled differently in Delhi, Beijing and Denver. Atmos shows the concentrations underneath and grades them the way your country does.

  • PM2.5, PM10, NO₂, O₃, SO₂ and CO in µg/m³
  • An alert up to two hours before PM2.5 is forecast to spike near you, judged against your own country's threshold
  • Local standards where they differ, including India's CPCB, China's HJ 633 and Thailand's PCD
  • Hourly forecasts so you can plan around the peak

The same air is legal in one place and a breach in another. Europe's current limit is five times what the WHO considers safe.

Ask Atmos

Ask what it means for you

Numbers are only useful if you know what to do with them. Ask in plain language and get an answer grounded in your local conditions right now.

  • “Is it safe to run this evening?”
  • “Why does my throat hurt today?”
  • Answers built from your live readings, not generic advice
