Remote sensing observations that utilize Global Navigation Satellite System (GNSS) signals have been used in geophysical research for decades. GNSS signals are particularly useful for various forms of geophysical research due to their high precision and insensitivity to clouds and precipitation. As such, GNSS observations such as radio occultations (GNSS-RO), GNSS reflections (GNSS-R), and the expanding network of ground stations provide high-quality global atmospheric and ionospheric retrievals useful in a wide variety of research. These observations also greatly contribute to numerical simulation systems and their data assimilation tools for accurate forecasts and early warning systems for natural hazards of many origins.
This session welcomes submissions including, but not limited to the following topics:
1. Neutral atmospheric research topics and related GNSS applications,
2. GNSS remote sensing technology advancement and novel observing concepts,
3. State-of-the-art atmospheric and surface property retrieval algorithm developments, and
4. Numerical weather prediction, ionospheric forecasting, and natural hazard now-casting applications of GNSS remote sensing products for data analysis and data assimilation impacts
