GOES-18 True Color RGB images created using Geo2Grid (above) showed smoke from Alaskan wildfires that had been transported southward over Kodiak Island and the northern Gulf of Alaska. Most of this smoke remained aloft — note that although Kodiak began reporting smoke late in the day, the surface visibility remained at 10 miles (below).
