Assessment of Accuracy of COSMIC and KOMPSAT GNSS Radio Occultation Temperature and Pressure Measurements over the Philippines

Atmosphere
Radio occultation (RO) is a technique used for measuring planetary atmosphere properties by orbiting satellites, like temperature, pressure, and water vapor.

Observing atmospheric rivers using GNSS radio occultation data

Abstract. Atmospheric Rivers (AR) are comparatively narrow regions in the atmosphere that are responsible for most of the horizontal transport of water vapor in the extra tropics, which are responsible for many extreme precipitation events and floodings at mid-latitudes, including Europe and the US. The critical role of ARs in global moisture transport

Review of Assimilating Spaceborne Global Navigation Satellite System Remote Sensing Data for Tropical Cyclone Forecasting

Remote Sensing
Global Navigation Satellite System (GNSS) Radio Occultation (RO) and GNSS Reflectometry (GNSS-R) are the two major spaceborne GNSS remote sensing (GNSS-RS) techniques, providing observations of atmospheric profiles and the Earth’s surface. With the rapid

Sub‐Seasonal Impact of GNSS Radio Occultation Data

Geophysical Research Letters
Abstract This study investigates for the first time whether the assimilation of the Global Navigation Satellite System Radio occultation (GNSS‐RO) data has a significant impact on the European Centre for Medium‐Range Weather Forecasts sub‐seasonal forecasts.

Principles of variational assimilation of GNSS radio occultation data

, 2003
The standard processing of the Global Navigation Satellite System (GNSS) based refractometric data performed by means of a space-borne GPS-receiver was based on the approximate derivation of the local vertical profiles of the atmospheric refractivity by means of the Abel transform.
