The High Performance Wireless Research and Education Network (HPWREN), a University of California San Diego partnership project led by the San Diego Supercomputer Center and the Scripps Institution of Oceanography's Institute of Geophysics and Planetary Physics, supports Internet-data applications in the research, education, and public safety realms.


HPWREN functions as a collaborative, Internet-connected cyberinfrastructure. The project supports a high-bandwidth wireless backbone and access data network in San Diego, Riverside, and Imperial counties in areas that are typically not well-served by other technologies to reach the Internet. This includes backbone locations, typically sited on mountain tops, to connect often hard-to-reach areas in the remote Southern California back country.

San Diego River Park Foundation Boulder Creek Preserve Environmental Monitoring Research Program

By Robert Mazalewski and Martin Offenhauer
Senior Technical Advisors at the San Diego River Park Foundation

The San Diego River Park Foundation (SDRPF) was created in 2001 to educate the public on the value of the San Diego River watershed and its relationship to our environment. Boulder Creek Preserve (the Preserve) is a 13.11-acre wildlife Preserve located in the headwaters of the San Diego River watershed 12 miles north of Descanso, CA. Boulder Creek, a tributary to the San Diego River, runs through the property. This component of the project involved the development and installation of an automated electronic water quality monitoring station in Boulder Creek connected to the internet.

20031026 The Morning After the Cedar Fire Ignition

This video is from the morning after the October 2003 Cedar Fire ignition, showing activities at the CDF Ramona Air Attack Base. It consists of 2078 images at their full 1288x968 pixel resolution. Many takeoffs and landings are shown while then at least some of the San Diego news media were claiming CDF aircraft were not flying, due to the Santa Ana winds. The HPWREN camera at the air base had only been installed a few months prior to that.
