Abstract Global Navigation Satellite System (GNSS) Polarimetric Radio Occultations (PRO) is an extension of the traditional Occultation (RO) technique that collects two linear and orthogonal polarization components occulting GNSS signals in order to retrieve precipitation information along with standard RO thermodynamic products. This has already been demonstrated ROHP experiment aboard PAZ satellite, a large platform launched 2018. In early 2023, Spire first three nanosatellites capable...

The Polarimetric Radio Occultation (PRO) technique involves tracking signals emitted by navigation satellites (GPS, Galileo, Beidou…) from a Low Earth Orbit (LEO) satellite as it rises or sets behind the Earth’s limb. This method extends capabilities of standard (RO) employing two orthogonal linear polarizations—horizontal (H) and vertical (V)—thereby providing relevant information about atmospheric hydrometeors. Furthermore, traditional RO products...

Currently, it remains a challenge to effectively monitor areas experiencing intense precipitation and the associated atmospheric conditions on global scale. This arises due limitations both active passive remote sensing methods. Apart from lack of observations in areas, quality some deteriorates when heavy is present, making difficult obtain highly accurate measurements thermodynamic parameters driving these weather events. However, there promising solution form Global Navigation Satellite...

Abstract. Polarimetric Radio Occultations (PRO) represent an augmentation of the standard Occultation (RO) technique that provides precipitation and clouds vertical information along with thermodynamic products. A combined dataset contains both PRO observable RO retrievals, resPrf, has been developed aim to foster use these unique observations fully exploit scientific implication having about cloud structures intrinsically collocated state atmosphere. This manuscript describes such detailed...

Lack of knowledge about the physical processes controlling heavy precipitation arises from limited number simultaneous observations vertical structure and its thermodynamic environment. These limitations are caused by degradation that signals some spaced-based sensors suffer in presence thick clouds or lack high resolution measurements.To overcome this problem, ROHP (Radio Occultation Heavy Precipitation) experiment provides high-quality profiles (temperature, pressure, water vapor etc.)...

A better understanding of the thermodynamics heavy precipitation events is necessary towards improving weather and climate models quantifying impact variability on precipitation. However, there are limited observations available to assess model structure within conditions.In 2009, Earth Observation Group at ICE-CSIC/IEEC conceived polarimetric radio occultations (GNSS-PRO) technique with aim obtain simultaneous measurements vertical its associated thermodynamic state. Based standard GNSS...

<p>Accurate prediction and modeling of heavy precipitation events remains an issue due to gaps in our understanding the physical processes underlying them. Such arise from limited number good quality observations that constrain thermodynamic parameters (e.g. temperature, moisture, etc.) within precipitation, since some space-based sensors are degraded presence thick clouds.</p><p>The Global Navigation Satellite System (GNSS) Polarimetric Radio...
