Assimilation of GNSS radio occultation observations in GRAPES
This paper reviews the development of the global navigation satellite system (GNSS) radio occultation (RO) observations assimilation in the Global/Regional Assimilation and PrEdiction System (GRAPES) of China Meteorological Administration, including the choice of data to assimilate, the data quality control, the observation operator, the tuning of observation error, and the results of the obser...
متن کاملLAGRANGE RO: A GNSS Receiver for Radio Occultation
A GPS Radio Occultation occurs when a transmitting GPS satellite, setting or rising behind the Earth limb, is viewed by a LEO satellite that carries on board a space-qualified GPS receiver. In this way, it is provided a vertical sounding of the atmosphere exploiting the relative motion between the GPS and the LEO satellites. The technique proved to be particularly precise in retrieving temperat...
متن کاملTesting Climate Models Using Infrared Spectra and GNSS Radio Occultation
The Climate Absolute Radiance and Refractivity Observatory will be a climate benchmarking mission intended to include instruments for measuring Earth’s atmospheric refractivity by GNSS radio occultation (RO), high spectral resolution thermal infrared spectra emitted from the Earth, and the spectrally resolved reflected shortwave spectrum. Climate benchmarking is necessary to establish a record ...
متن کاملSpaceborne GNSS Radio Occultation Instrumentation for Operational Applications
Radio occultation (RO) instruments using GNSS signals are specialised spaceborne receivers designed to provide highly accurate measurements from which one can derive vertical profiles of the temperature, pressure and humidity in the atmosphere, as well as profiles of electron content in the ionosphere. A family of operational RO instruments is being developed for a number of European space proj...
متن کاملTriG - A GNSS Precise Orbit and Radio Occultation Space Receiver
The GPS radio occultation (RO) technique [1] produces measurements in the ionosphere and neutral atmosphere [2] that contribute to monitoring space weather and climate change; and improving operational weather prediction. The high accuracy of RO soundings, traceable to SI standards, makes them ideal climate benchmark observations. For weather applications, RO observations improve the accuracy o...
