GLOBE Urban Heat Island Effect (UHIE)-Surface Temperature Field Campaign Update

GLOBE community members engaging in the October 2021 UHIE, focusing on studying artificial turf versus grass soccer and football fields.

The October 2021 GLOBE Urban Heat Island Effect (UHIE)-Surface Temperature Field Campaign wrapped up, with over 1,200 observations submitted from 43 schools. Over 50 percent of the data was submitted in the final two weeks of December.

Dr. Kevin Czajkowski (University of Toledo, Ohio) would like to thank everyone who participated in the event. “Just to show you what can be done with the GLOBE observations, we grouped together locations in which the surface temperature of grass and asphalt were taken nearby each other. You can see on this graph that the asphalt was warmer than the grass in most cases. In only two cases was the asphalt colder than the grass. Can you guess what conditions would lead to that?”

“We found that many schools kept taking observations right through November and into December. So far in December, there have been 710 surface temperature observations taken. It is great to see so many students outside taking observations.”

Over the next couple of months, Dr. C will be transitioning the UHIE campaign to an Intensive Observation Period (IOP), which will take place during October, December, and March.
