GNSS-RO Sounding in the Troposphere and Stratosphere

2022
The use of Global Navigation Satellite System Radio Occultations (GNSS-RO) for vertical sounding of temperature and moisture in the atmospheric column has become a standard practice of many numerical weather prediction (NWP) centers. The introduction of this observation has seen broad positive impact on analyses and forecasts.

Ionospheric Sounding Using GNSS-RO

2013
The GNSS signal will be bent from GNSS transmitters and LEO satellites when the signal goes through Earth’s ionosphere. With the improvement of GNSS-RO technique and more GNSS-RO missions, ionospheric parameters can be retrieved, including TEC and ionospheric electron density.

Atmospheric Sensing Using GNSS RO

2013
In this chapter, the basic methodology to derive the geophysical parameters from GNSS RO refractivity will be explored in Sect. 6.1. In the following Sect. 6.2, the detailed characteristics of RO observables will be studied. The science application utilizing such RO derived geophysical parameters, spanning from atmospheric dynamic process to weather ...

Development of GNSS-RO and EDTP sensors onboard microsatellite for ionosphere monitoring

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
Chiba University develops two microsatellites called GAIA-I and GAIA-II. GAIA-I payload is GNSS Radio Occultation (RO) sensor and Electron Density — Temperature Probe (EDTP) for Ionosphere monitoring, and GAIA-II payload is Circularly Polarized Synthetic Aperture Radar (CP-SAR) for global land deformation monitoring.

A multi-center exercise on the sensitivity of PAZ GNSS Polarimetric RO for NWP modeling

2023
A better understanding of the thermodynamics of heavy precipitation events is necessary towards improving weather and climate models and quantifying the impact of climate variability on precipitation. However, there are limited observations available to assess the thermodynamics model structure within heavy precipitation conditions.In 2009, the Earth ...
