Burn scars over Canada revealed by JPSS VIIRS imagery
Given all the smoke over United States, one might ask: “Just how much acreage has burned over Canada?” NOAA-21 VIIRS False-color imagery from 28 June, toggled above with True-color imagery, reveal very large burn scars over Quebec to the east of James Bay. In the False-color imagery, the burnscars have a brownish hue such as the oval feature just west of Laforge-un at the eastern edge of the image. That scar also shows active burning along its southwestern edge, and its smoke plume extends southwestward to the burnscar that is southeast of Sakami. It is very difficult to discern the burn scars in the True-color imagery. The smoke plumes themselves are more apparent in True-color vs False-color.
VIIRS ‘False Color’ imagery uses bands M11, I2 and I1 for the red/green/blue components of the RGB. (link) ‘True Color’ imagery uses M5/M4/M3 and the I1 band can be used to sharpen the imagery.
