From Source to Product Signal

Test a Product Idea in Four Steps

GeoMet WCS serves FireWork's RAQDPS surface wildfire-smoke PM2.5 layer as GeoTIFF. Start with a one-degree coverage request. Values are modeled mass concentrations in kg/m3, not observed AQI; retain the valid and model-run times for decisions.

1

Check the Setup

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

Access the Data

  1. 1.Read ECCC's FireWork forecast and Open Government Licence pages.
  2. 2.Request a small GeoTIFF coverage for the exact wildfire-smoke layer.
  3. 3.Inspect the model units and dated WCS dimensions before displaying values.

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install requests

import requests

params = [
    ("SERVICE", "WCS"), ("VERSION", "2.0.1"),
    ("REQUEST", "GetCoverage"),
    ("COVERAGEID", "RAQDPS.Sfc_PM2.5-WildfireSmokePlume"),
    ("FORMAT", "image/tiff"), ("SUBSETTINGCRS", "EPSG:4326"),
    ("SUBSET", "x(-76,-75)"), ("SUBSET", "y(45,46)"),
]
response = requests.get("https://geo.weather.gc.ca/geomet", params=params, timeout=30)
response.raise_for_status()
assert response.content[:4] in (b"II*\x00", b"MM\x00*")
print("FireWork GeoTIFF bytes:", len(response.content))

Test a Useful Signal

Inspect a FireWork Smoke Coverage

Show a small, dated FireWork smoke-model view with clear units and provenance.

  1. 01Request one GeoTIFF coverage over a small area.
  2. 02Read its model and valid times before comparing forecast values.
  3. 03Explain why modeled PM2.5 cannot be labeled as a local monitor observation.
