PICO
Complementary middle-atmosphere sounding techniques—such as infrasound, lidar, radar, microwave spectrometry, and mesospheric airglow observations, further strengthened by satellite measurements—have become significantly more accessible over the past decade. It is expected that developing multi-instrument platforms will expand the community involved in operational infrasound monitoring for near-real-time observation of high-impact natural hazards—including volcanic eruptions, earthquakes, meteoroid entries, and bright fireballs—while creating new opportunities for atmospheric remote sensing research, such as improving gravity wave parameterizations.
In particular, global and regional infrasound station networks have proven highly effective in detecting and locating a wide range of natural and anthropogenic phenomena. Recent studies have shown that multi-technology analyses provide foundations for addressing geophysical inverse problems, enabling novel probing of both global-scale and small-scale structures in the middle atmosphere for enhanced weather prediction and climate modeling.
In addition to data-driven contributions, this session invites model-based papers dealing with the dynamics of the middle atmosphere across scales and altitudes, as well as its predictability. We welcome contributions on the characterization of atmospheric phenomena (gravity or planetary waves for example), using complementary observational methods across both local and global scales. Contributions addressing advances in wave propagation modeling, signal processing, and machine learning applications are also of great interest. Additional areas of focus include the development of derived data products and services for scientific and civilian use, as well as innovative instrumentation, including sensors deployed on mobile or elevated platforms such as balloons on Earth or other planets. Seismo-acoustic studies investigating the coupled Earth–ocean–atmosphere system, particularly focusing on ionospheric responses to processes originating from the ocean and solid Earth, are also encouraged.
