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.

Triangulating Meteors with HPWREN Cameras

December 1, 2021

The HPWREN cameras often capture images of meteors streaking through the sky. A particularly good example was identified by Ross Seibert in one image from the west-facing camera at Lyons Peak the night of November 9.


Various HPWREN videos are available at /user/hpwren/videos. Many of these are live or post-processed time-lapse videos, including those related to fires, weather conditions, flooding, and other public safety issues.

Included is also a short 20 year summary video related to the article.

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.
