TitanSkies
Explore wildfire smoke forecasts, air-quality readings, and reported fire context across North America.
Data Sources
TitanSkies combines two smoke models with preliminary monitoring data and agency-reported wildfire context. Individual inputs can be stale or unavailable; forecasts are not observations or emergency alerts.
This is a reviewed source inventory, not a live feed-health report. Availability depends on each app's configuration and the provider's current service.

Forecasts
ECCC FireWork
Role: Base smoke-concentration forecast for the integrated map.
Availability: Configured public WCS forecast; a failed or stale run can retain a dated prior forecast.
Coverage: Canada and adjoining areas covered by the FireWork model.
A FireWork-specific guide has not passed the Data catalog review.
NOAA HRRR-Smoke
Role: U.S. smoke forecast enhancement where it exceeds the FireWork base.
Availability: Configured public GRIB forecast; freshness and fallback are checked per run.
Coverage: United States model domain.
A HRRR-Smoke-specific guide has not passed the Data catalog review.
Observations
EPA AirNow
Role: Provider-reported PM2.5 AQI at participating monitors; TitanSkies does not recalculate these AQI values.
Availability: Optional: requires AIRNOW_API_KEY. Missing key or provider failure makes this monitor set unavailable or dated.
Coverage: Participating U.S. monitoring sites.
B.C. ENV air quality
Role: Hourly PM2.5 concentrations converted by TitanSkies to U.S. EPA NowCast AQI.
Availability: Configured public observation feed; stations and timestamps may be incomplete or stale.
Coverage: British Columbia stations.
A guide for this B.C. hourly feed has not passed catalog review.
INECC SINAICA
Role: Hourly PM2.5 concentrations quality-screened and converted to U.S. EPA NowCast AQI.
Availability: Gated by SINAICA_ENABLED; disabled sources and failed reads are reported as unavailable or dated.
Coverage: Participating Mexico monitoring stations.
A SINAICA-specific guide has not passed catalog review.
ECCC Air Quality Health Index
Role: Canadian AQHI observations, kept on the AQHI scale rather than converted to AQI.
Availability: Configured public feed; observations can be missing or stale.
Coverage: Participating Canadian stations.
An AQHI observation guide has not passed catalog review.
Wildfire context
NIFC WFIGS
Role: Agency-reported U.S. wildfire incident points and perimeters; they do not identify a smoke plume's origin.
Availability: Configured public service with per-run freshness checks and dated fallback.
Coverage: United States incidents and perimeters.
A WFIGS incident-layer guide has not passed catalog review.
NRCan CWFIS
Role: Agency-reported Canadian wildfire incident points and perimeters.
Availability: Configured public service with per-run freshness checks and dated fallback.
Coverage: Canada incidents and perimeters.
A CWFIS incident-layer guide has not passed catalog review.
Pinned geography
Natural Earth oceans and populated places
Role: Ocean mask for smoke coverage and city candidates for ranked smoke and AQI results and search.
Availability: Pinned 50m ocean and 10m populated-place source artifacts used during the geography build, not a live feed.
Coverage: North America within the generated map and city catalog.
