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.

August 2021 - Summer Rain

High school student Colin Wessels in Idaho did a summer project with CAIDA and HPWREN on the impact of the pandemic on patterns of air traffic, based on ABS-B data collected via a receiver on Mt. Woodson that is connected to the HPWREN network. This article is his report on the project.

How Coronavirus Affected Air Traffic in Southern California

Introduction

This study is based on the speculation that the Coronavirus outbreak significantly affected commercial air travel. By February 2, 2020, just 2 days after the World Health Organization declared a public health emergency, air travel to and from China was restricted. As cases continued to rise, air travel continued to be restricted worldwide. When I was given data on aircraft telemetry in the southern California area, I was curious if these restrictions would be reflected in the data.

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:
