Long-term Changes in Global Tropopause Characteristics from GNSS-RO Observations
The tropopause is an important boundary (or transition layer) for many studies in the atmospheric sciences and is an indicator of global climate change. Numerous characteristics of the tropopause have been shown to exhibit significant long-term change over the most recent 40+ year period, including height, temperature, and the occurrence of multiple ...Cameron Homeyer, Emily Tinney

Precise Orbit Determination of the Spire GNSS-RO Constellation
This study introduces the raw observation approach for precise orbit determination (POD) of commercial 3U CubeSats equipped with a STRATOS receiver that collect dual-frequency GNSS observations. Different Spire CubeSats, each with different orbital characteristics and inclinations, are analyzed by processing reduced dynamic and kinematic orbits from ...SHAFIEI, Parisa +2 more

Comparison of reference upper-air GRUAN and homogenized RHARM data with GNSS-RO
The study of thermodynamical variables, such as temperature and relative humidity in the upper troposphere/lower stratosphere (UT/LS), is one of the key elements for the study of climate change. Several studies estimated trends both regionally and globally in the UT/LS, using both satellite and ground-based data and different measurement techniques ...Fabrizio Marra +5 more
