Urban Heat Island Webcasts and Conference Calls

Next Urban Heat Island Webcast:
No webcasts are scheduled at this time. Future webcasts will be planned based on requests from the heat island community. To submit suggestions for future topics, please email Neelam R. Patel at Patel.neelam-r@epa.gov.
EPA holds free, national, urban heat island (UHI) webcasts. Prior to 2008, these meetings were held via conference call. Through these webcasts, and former conference calls, stakeholders from around the country inform each other of their urban heat island-related work. Scientists, practitioners, industry representatives, and government officials and staff all participate.
Presentations and other materials from these webcasts and conference calls are posted below, organized by topic. Note that some presentations are relevant to several topics and thus may be listed more than once. The most recent webcast is also listed by date.
- Most Recent Webcast
- Measuring and Modeling Urban Heat Islands
- Heat Island Impacts
- Mitigation
- Pre-2005 Conference Calls
Contact Us, if you would like to participate in future Webcasts. To help keep you up to date, you may also wish to sign up for EPA's Urban Heat Island Newsletter.

*Prior to 2005, the conference call summaries were titled "Heat Island Reduction Initiative (HIRI) News" and were prepared as PDFs. These files are organized by date instead of by topic due to the limitations of the PDF format. The headings in the "Topics" highlight just some of the material discussed during the conference call.
