Delaware air quality remains good despite haze generated by California wildfires.
The AirNow index from the Environmental Protection Agency showed the state in the green territory.
WPVI-TV reported the region is seeing an upper-level haze as particles from the fires are transported by the jet steam at an altitude of 25,000 to 35,000 feet.
If the haze was not present, skies would be a brighter blue.
NASA satellite images show the haze from “aerosols” (tiny particles) spreading across the nation from west to east. The space agency warned that the aerosols can be hazardous at low altitudes.
The joint NASA & @NOAA Suomi NPP satellite continues to monitor wildfires in the western United States. New images show the winds have changed again, with smoke and small particles suspended in the air (aerosols) moving across the continental U.S.: https://t.co/tlMce2rxIT pic.twitter.com/EmISBArc4F
