Photo showing Stacey Henry, founder of the Delaware Resilience Hub, and her daughter, Mylee, volunteered to collect temperature, humidity, time and location data for the 2023 NOAA-supported Urban Heat Island mapping campaign in Wilmington, Delaware and surrounding townships. They joined other volunteers who attached sensors to their cars to collect the data that was used to create a detailed map of the hottest areas in their community.

On September 27, 2023, the VIIRS instrument onboard NOAA’s JPSS satellites captured this GeoColor imagery of Canadian wildfire smoke being pulled across the Atlantic Ocean by two areas of low pressure—one swirling system can be seen in the left of this image and the other, deemed Storm Agnes by the UK Met Office, is on the right near Ireland and the United Kingdom. GeoColor imagery provides a close approximation to what you would see with your naked eye from outer space.
