Observed thermal detection

Thermal detection near Ivano-Frankivs'k

Measurable thermal activity. No satellite detection does not mean an area is safe. Cloud, sensor timing and heat below a sensor’s threshold can hide activity.

Where the measurements are

Drawn server-side from the public event read model. Every mark is a measurement: nothing here is interpolated, smoothed or inferred.

What each mark means

Footprint at this scaleVIIRS (NASA) 375 mMeteosat (EUMETSAT) ≈2 km · not drawn

  • VIIRS (NASA)375 m—

    Measured positions. Drawn at true footprint scale, brightest layer.

  • Meteosat (EUMETSAT)≈2 km—

    Measures how much energy is radiated, which is what sizes the glow. Its individual pixel positions are not stored, so no Meteosat footprint is drawn — inferring one from the sharper layer would put a detection pixel on ground nobody measured.

  • True geographic scale, corrected for latitude. Frame is about 48 km across.
  • The glow means “an event, roughly here”. Its area follows the measured power and its radius is capped, because an uncapped one would assert a burnt extent nobody measured. The number carries the magnitude.
  • Grey is what a later pass has superseded. Colour means the most recent sharp measurement, and it never fades with the clock — only newer knowledge demotes it.
  • Coastline, lakes and borders come from a generalised map with about 1,7 km between vertices, so treat every line as the shape of the geography and not as a surveyed boundary. It is drawn under the data and never over it.
  • The dashed line is a modelled satellite ground track through the pass that produced the coloured detections — real published orbital parameters, measured pass time, modelled geometry. The swath is 3060 km wide, so where the satellite actually looked from inside it is unknown.

Verification ladder

  • SeenObserved

    A satellite observed a thermal anomaly here. Repetition belongs at this step: seeing the same thing many times separates noise from signal, but it does not separate heat from bright ground. Observed by: VIIRS (NASA).

  • ConfirmedObserved

    The anomaly carries measured energy or a 375 m position — the calibrated Meteosat fire product, or a VIIRS detection. Persistence alone never lights this step, because sunlit dry ground is persistent by nature.

  • QuantifiedObserved

    The heat here has a number on it — radiated power, in megawatts — and the number is what lets one reading be compared with another from the same time of day, day by day. Between measurements it says nothing. Measured by: VIIRS (NASA).

What the ground under this event looks like

Almost every heat reading here — 300 of 308 — falls on ground our register already lists: it has been warm on repeated days without ever running hot. That is what a fixed installation looks like from orbit. It is probably an installation rather than a wildfire, but we cannot tell the two apart from satellite data alone, so this page does not claim either. Measured 30 sept. 2026.

What each sensor measured

Meteosat looks every ten minutes; VIIRS passes a few times a day. The contrast is the point — between sharp passes there is no new sharp knowledge, only the ten-minute layer.
