*Description:*Several natural phenomena on Earth and in space, such as
tsunamis, volcanic eruptions, earthquakes, and geomagnetic and solar
storms leave a readily-detectable signature in the Earth's ionosphere.
Monitoring the ionosphere in real-time can therefore greatly enhance our
early warning systems for these events. Traditionally, the ionospheric
response to these sources has been studied several days to weeks after
the event occurs. For the ionosphere to be used as a medium for hazard
warning, it must be monitored in near-real-time with analyses provided
in a timelier fashion.
The GNSS-based Upper Atmospheric Realtime Disaster Information and Alert
Network (GUARDIAN) is a state-of-the-art near-real-time monitor designed
to provide estimates of the ionospheric line of sight total electron
content (TEC) from L-band radio-frequency signals transmitted by the
Global Navigation Satellite System (GNSS) satellites. We combine, clean,
and filter phase data to generate TEC time-series for multiple
constellations from nearly 90 stations around the Pacific Ring of Fire
with an approximate latency of 3 minutes. GUARDIAN builds on JPL's
Global Differential GPS (GDGPS) capability and the International GNSS
Service (IGS) network, which aggregate GNSS phase data from a network of
real-time worldwide stations.
In this presentation, we will discuss the architecture of the GUARDIAN
system, highlight several examples and use cases, and share future plans
for its development, with the hopes of enhancing existing hazard warning
frameworks to safeguard communities around the world.
