Ground Smoke Effects

Canadian wildfires continue to influence sky brilliance and even air pollution in Iowa. The two images above show sunrise at 6:14 am on Tuesday, July 7, 2015, as seen from Boyson Road, just west of Interstate 380 in Hiawatha. Smoke from the wildfires was borne by a northern cold front and actually pushed it toward the ground, making its odor noticeable and resulting in low air quality advisories. iPhone 6-plus camera.
