Light. Colour How do we see colours? White light, the light you see from globes, fluorescent tubes or the sun, is made up of lots of different colours.

Visible and Infrared (IR) Weather Satellite Interpretation 1. Visible satellite images are coded from black to white according to the amount of reflected.

Thermal radiation Any object that is hot gives off light known as Thermal Radiation.  The hotter an object is, the more light it emits.  As the temperature.

VIIRS and the Fort McMurray Fire VISIT Satellite Chat (18 May 2016) Curtis Seaman, CIRA

Outline Look at VIIRS imagery of Fort McMurray Fire Discuss “saturation” and “fold-over” Introduce “Fire Temperature RGB” References

Spatial Resolution (m) @ nadir VIIRS Bands for Fires VIIRS Band Central Wavelength (μm) Band Explanation Spatial Resolution (m) @ nadir M1 0.412 Visible/ Reflective 750 m M2 0.445 M3 0.488 M4 0.555 M5 0.672 M6 0.746 Near IR M7 0.865 M8 1.240 Shortwave IR M9 1.378 M10 1.61 M11 2.25 M12 3.7 Medium-wave IR M13 4.05 M14 8.55 Longwave IR M15 10.76 M16 12.01 DNB 0.7 Visible / Reflective 750 m across full scan I1 0.64 375 m I2 0.87 I3 I4 3.74 I5 11.45 VIIRS has 9* bands that detect fires/flares/hot spots M-12, M-13, I-4 are best for fire detection M-11 detects moderately active fires M-10, I-3, M-15, I-5 detect only the hottest, largest fires DNB detects visible light from fires at night

Brightness Temperature (K) M-13 vs. I-4 M-13 I-4 Warmest pixel: 487 K “Cold” pixels near the center of the fire are due to saturation and “fold-over”. 750 m resolution 375 m resolution 20:20 UTC 3 May 2016 I-4 is higher resolution, but has a low saturation point (367 K) M-13 is a dual-gain band with a high saturation point (+600 K) Brightness Temperature (K)

Fire Temperature RGB Fire Temperature RGB combines the short/mid-wave IR bands to aid fire detection M-10 (1.61 µm), M-11 (2.25 µm) and M-12 (3.7 µm) Hot spots detected in M-12 show up red Hot spots detected in both M-12 and M-11 appear orange to yellow Hot spots detected in all three bands appear white (maybe even bluish if fold-over is present in M-12) 20:20 UTC 3 May 2016 Liquid clouds appear blue, ice clouds appear dark green, bare ground appears purple/maroon, snow/ice/water appear black
