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.

The below link includes audio, transcripts and presentations from this webcast.
