| Model | Peak PM2.5 | Peak around |
|---|---|---|

Model values are for the nearest forecast grid cell to Jasper; FireSmoke, FireWork and HRRR are independent and often disagree — treat the highest available value as the cautious planning number.
Observations and NowCast are total PM2.5 — wildfire smoke plus every other source — as regulatory monitors measure it, and FireWork models that same total. FireSmoke and HRRR-Smoke estimate the wildfire contribution only, so they read lower than the monitors whenever other sources matter. The optional map plume surfaces are likewise fires-only.
Little smoke at the surface or overhead.
● At the ground · ● Overhead (relative)
Overhead smoke dims the sun but is not what you breathe. The dashed line is the column total scaled to a typical mixed plume, so it is comparable in shape, not in units · Data: ECCC FireWork
Within 150 km, agencies report 1 Being held · 6 Under control.
No out of control fires are reported within 150 km.
Proximity and wind direction do not prove that a fire caused smoke at this location. Sources: BC Wildfire Service in British Columbia; Natural Resources Canada CWFIS elsewhere.
