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.

HPWREN Cameras Used to Demonstrate the Effects of Light Pollution

I have created a short video comparing the views of the stars from the HPWREN cameras on Mt. San Miguel (overlooking the San Diego–Tijuana metropolitan area) and at the Mount Laguna Observatory (44 miles east of downtown San Diego). The videos are intended to show that while the same stars shine over both sites, the sky glow from city lights strongly obscure the stars above Mt. San Miguel.

Fires, weather conditions, flooding, and other public safety conditions are scenarios where real-time sensor data distributions can become important aspects for situational awareness. HPWREN can now provide live feeds from most of its cameras, in addition to the post-processed videos shown at:

20210629 Cloud domes buildup in the San Diego Mountains area

This is a time lapse animation of once-per-minute images which focus on cloud domes buildup in the San Diego Mountain area on 29 June 2021, as seen by four HPWREN cameras on Toro Peak and Monument Peak in the top row, as well as Cuyamaca Peak and Lyons Peak in the bottom row. The time series extends from 9:00 to 21:00 and is shown at 10 frames per second on a 4k canvas.

This video is best viewed on a large high resolution screen.
