Investigating equatorial waves with high-density ROMEX GNSS-RO observations

Remote sensing from satellites provides a powerful means of observing the Earth’s atmosphere with global coverage and high vertical resolution. Among these techniques, Global Navigation Satellite System radio occultation (GNSS-RO) offers a low-cost approach that delivers large volumes of high-quality atmospheric temperature profiles. While several tens

Impact of GNSS RO Data on the Prediction of Atmospheric River Events: A ROMEX Experiment

Weather and Forecasting
Abstract The assimilation of Global Navigation Satellite Systems (GNSS) radio occultation (RO) data has been shown to improve the prediction of atmospheric rivers (ARs), which are key drivers of heavy precipitation along the U.S. West Coast. This study builds on prior research by evaluating the impact of the Radio Occultation Modeling

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 ...

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 ...

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 ...
