Global Navigation Satellite System Radio Occultation (GNSS-RO) observations provide near-vertical profiles of refractivity, temperature, and moisture from the boundary layer to the stratosphere with high vertical resolution, global coverage, and all-weather capability. The value of these observations to the atmospheric science community has been demonstrated over the past two decades. RO measurements are routinely assimilated into numerical weather prediction models without bias correction and are well suited to long-term climate monitoring. This session aims to explore recent scientific advancements using GNSS-RO data in the neutral atmosphere. An emphasis will be placed on science studies using data from the FORMOSAT-7/COSMIC-2 (C2) constellation. The C2 constellation provides a unique opportunity to study the lower latitude neutral atmosphere, owing to high signal-to-noise ratio and dense sampling throughout the tropics. Science utilizing other recent missions such as Sentinel-6, GRACE-FO, and commercial RO providers is also sought.
