<div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">We would like to invite you to the
<b>final conference for phase 2 of DARPA’s AtmoSense program</b> (<a href="https://www.darpa.mil/research/programs/atmosphere-as-a-sensor">https://www.darpa.mil/research/programs/atmosphere-as-a-sensor</a> and <a href="https://www.darpa.mil/news/2020/atmosphere-global-sensor">https://www.darpa.mil/news/2020/atmosphere-global-sensor</a>).
The conference will be held in Daytona Beach, FL, April 16-17, 2025; further logistical details will be forthcoming via later email(s).</div>

<div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">The <b>AtmoSense AIRWaveS</b> project spans ten organizations with a focus on modeling and detection of modest ground-level impulsive disturbances through remote sensing (ionospheric HF, GPS TEC measurements,
and pressure sensors). Signals from such sources have duration and amplitude that place extreme requirements on numerical models (both in terms of resolution and coupling of neutral to plasma gases) and push detectability limits of TEC and HF measurements.
To address these challenges, the AIRWaveS team has worked with technical advances in adaptive mesh refinement, coupling of different numerical codes (physics and solvers) to create multi-physics simulation framework(s), and development of synthetic data capabilities
to study atmosphere-ionosphere disturbances. Field experiments from phase 2 have demonstrated detectability of signals of interest in various radio diagnostics as well as suggested specific approaches to improve chances of detection and estimation of source
characteristics (e.g. amplitude, timing, geolocation) – while using the new modeling tools to help interpret signals of interest.</div>

<div style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">The intent of this conference is to: (a) summarize key accomplishments from phase 2 of the AtmoSense program (i.e. new field tests and numerical applications), and (b) explore and foster potential
connections of this program to the broader research community, e.g. Heliophysics and space weather, fluid modeling, applied mathematics and numerical methods, remote sensing, seismoacoustics, infrasound, and other fields. To this end, this meeting will feature
talks from AtmoSense phase 2 performers alongside presentations from other attendees in related/adjacent fields. We hope this will encourage and prioritize new discussions among different groups and spark project ideas in and across these various disciplines.</div>

We plan to have a hybrid/asynchronous option, but in-person contributions will be prioritized.</div>
