2020 was a year to remember for HPWREN and everyone else. The first two and a half months were fairly normal with routine maintenance and upkeep to maintain services through the winter months when generally there is little fieldwork. One significant accomplishment was the installation of the SDGE supported San Juan Hills site including ALERTWildfire and HPWREN cameras in January 2020.
March 17, 2020, marked the beginning of the Covid lockdown in California, reducing field work activities to essential activities to keep HPWREN, ASAPNet, and ALERTWildfire cameras functioning, while all personnel sheltered in place at home working remotely. During the following year, HPWREN adapted to each new set of restrictions and requirements while keeping services working and making strategic improvements to the system. In the light of one year under Covid, this somewhat late annual report will cover through the first year of Covid restrictions.
In spite of the challenges, this past year had some major accomplishments. Two of our most challenging sites (Toro Peak and Lyons Peak) were rebuilt. In addition, Los Pinos was also rebuilt, completing the goal of providing more resiliency to the southern part of HPWREN. From a wildfire observation perspective, Cuyamaca Peak, Otay Mountain, San Miguel, and Sagebrush Flats received new and/or upgraded cameras. In partnership with ALERTWildfire and LA City Fire Department, five new ALERTWildfire camera sites were deployed in the Santa Monica Mountains. The newly installed sensors at Cuyamaca Peak and upgraded sensors at Lyons Peak both provided enhanced situational awareness during the Valley Incident that burned in the Cleveland National Forest and CAL FIRE San Diego Unit in September, 2020. This included data provided through new weather sensors, Mobotix Cameras, and the ALERTWildfire Axis cameras.
One of the remarkable attributes of HPWREN is the ability for end users to utilize the data collected through HPWREN to create interesting results. In 2020, Prof. Robert Quimby, Director of the Mt Laguna Observatory, created interesting videos using HPWREN cameras highlighting basic astronomical observations such has how the sun moves over an annual cycle, the motions of planets against the fixed stars, the movement of Comet Neowise, and others.
Overall, 2020 was another busy year for HPWREN. This article highlights significant activities undertaken in 2020 and some predictions for early 2021 activities.

II. Public Safety Service Improvements
HPWREN has added new fire cameras, new WiFi capabilities, new fixed wireless links, and various network upgrades to allow for increased bandwidth to our systems from our collaborators. For more specific network upgrade details, see the section below “IT Infrastructure Upgrades, Services and Support”.

In support of the growing ALERTWildfire community, HPWREN provides high quality Internet connectivity using fixed wide area wireless technology connected to multiple regional Internet gateways at sites in San Diego, Orange, Los Angeles, and Santa Barbara Counties.
III. Public Outreach
The many ways we have reached out to the public this past year include:
Posted numerous interesting and informative YouTube videos
See 45 or so 2020 videos (animations, split screens, surround views, etc.) of fires and interesting events captured by HPWREN cameras at https://www.youtube.com/user/hpwren/videos.

IV. IT Infrastructure Upgrades, Services and Support
Infrastructure improvements in 2020 include:
Added 126TB of storage to production camera image web servers (72TB on c1 and 54TB on c2) providing a c1+c2 total of 375TB
Received permission from CalOES to use their Santiago Peak tower, allowing the establishment of Santiago Peak as an HPWREN radio gateway linking Orange, Riverside and San Diego counties using fixed wireless technologies. This also paves the way for additional HPWREN wireless/CENIC cross county path diversity provided by UCSD, UCI, UCR and SDSU campuses
Upgraded antennas and radios at
Refreshed backbone equipment at existing sites. Equipment included routers, switches, power supplies, cabling, UPS etc.:

V. Research and Development
HPWREN infrastructure supports a variety of research and education projects and we are always looking for new ways to do things or new capabilities to add. The more significant activities this past year include:
The HPWREN Fire Ignition Library (FIgLib) uses sequences of wildland fire images as seen from fixed cameras at HPWREN sites. It contains hundreds of such sequences of different fires or different cameras, where a camera may even be separate imagers for color, or monochrome with more light and near-IR sensitivity. The primary purpose of this large archive, many gigabytes in size, is the creation of baseline data sets for 40 minutes before and after individual fire ignitions for neural network training, including neural network based detections of wildland fire ignitions based of content within a single or across multiple images. See /HPWREN-FIgLib/ for more details.
This data set was significantly enhanced during 2020, and HPWREN has collaborated with multiple researchers and developers who are applying to to training neural networks. In addition, the UCSD WIFIRE (wifire.ucsd.edu) project and NSF Sage (sagecontinuum.org) orchestrated a collaboration with the Argonne National Laboratory (https://anl.gov/), where ANL is undertaking the laborious task of labeling the hundreds of fire ignition sequences currently in FIgLib.
Continued next generation “getcams” image fetching environment development, including testing with multiple distributed storage options across regions. The experimental system runs as a service, spawning and maintaining a single, long running process per camera. We have been able to handle concurrent fetching from 150 cameras once per minute using a single 4 Core 4 GB VM. Image load can now also be spread across multiple servers as needed to support flexible scaling. The prototype system is being tested at both UCSD and UCI.
PRP (Pacific Research Platform) and Calit2 (at UCSD and UCI) are supporting the establishment of a Calit2@UCI repository for Orange County HPWREN fire camera images. This Calit2/HPWREN collaboration was proposed near the end of 2019 and implemented during 2020. This experiment supports
