@jo58joy: How much of the sky is actually hazy with smoke or dust? This is CAMS total aerosol optical depth - smoke from wildfires, dust storms, and pollution haze - for a full year, draped on the unfolded globe so every continent stays in view at once. The hazy share of Earth's atmosphere swings from about 7 million square kilometers on a clear stretch to nearly 44 million at the worst of it. Can you spot the wildfire season just by watching the glow move? Data: Copernicus CAMS, daily total aerosol optical depth. #dataviz #satellite #climate #wildfire #dust
