Applications now being accepted for 2022 Urban Heat Island Mapping Campaigns

Applications now being accepted for 2022 Urban Heat Island Mapping Campaigns

The National Integrated Heat Health Information System (NIHHIS) and CAPA Strategies are now accepting applications from organizations interested in participating in the 2022 cohort of the Urban Heat Island (UHI) mapping campaigns. Over the past four years, more than three dozen cities across the United States. have participated in the UHI campaign program to map the hottest parts of their communities. Cities in 11 states participated in the 2021 campaign, which finished data collection in September. Mapping reports will be released on a rolling basis through December. 

NOAA will provide funding to CAPA Strategies to support campaigns in approximately 8-10 communities in 2022. Additionally, there are three new features planned for the 2022 mapping campaigns:

Additional monitoring products will be piloted in a few cities. While the standard campaigns provide a good snapshot of how temperatures vary in a city/county on a hot day, adding stationary sensors to the campaign can provide a longitudinal look at how these spatial patterns also vary over time under varying weather conditions. 
Environmental Justice will be another factor considered when prioritizing applications, as the UHI mapping program is now a covered program under the Biden Administration’s Justice40 initiative. The campaign cities will track and report on the allocation of benefits to Environmental Justice (EJ) communities. 
The NIHHIS-CAPA Urban Heat Island mapping campaigns will be open to global cities for the first time. For the 2022 mapping season, 1-2 campaigns will be selected from cities outside of the United States. We are partnering with the Global Heat Health Information Network (GHHIN) to reach communities in other countries.

Applications for support are due by 5 PM Eastern on Friday, January 14, 2022. Applicants will be notified of the outcome of their requests  by early February, 2022.
