From Source to Product Signal

Test a Product Idea in Four Steps

The EEA Air Quality Index publishes a station metadata index, hourly map, and per-station detail JSON. Start with one reviewed Austrian station and two hours; modeled gap fills must not be presented as measurements, and one station does not establish destination-wide air quality.

1

Check the Setup

  • Python 3.10 or newer
  • An internet connection
  • The requests Python package
2

Access the Data

  1. 1.Read the EEA AQI methodology and legal notice.
  2. 2.Fetch one station-detail artifact from the official AQI data lake.
  3. 3.Inspect the observation and modeled flags for two hourly records.

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install requests

import requests
from datetime import datetime, timezone

url = ("https://dis2datalake.blob.core.windows.net/airquality-derivated/"
       "AQI-noRunningMeans/current/AT60118.json")
response = requests.get(url, timeout=20)
response.raise_for_status()
now = datetime.now(timezone.utc)
observed = []
for hour, row in response.json().items():
    pollutant = row.get("culprit")
    if (pollutant and datetime.fromisoformat(hour.replace("Z", "+00:00")) <= now
            and row.get(f"modelled_{pollutant}") == 0):
        observed.append((hour, row))
for hour, row in sorted(observed)[-2:]:
    print(hour, row.get("aqi"), row.get("culprit"))

Test a Useful Signal

Inspect Station AQI Context

Compare two station hours while retaining modeled-value provenance.

  1. 01Fetch one station's dated hourly values.
  2. 02Display the culprit pollutant and model flag beside AQI.
  3. 03Explain why a modeled fill or one station is not a local measurement.
