This project uses the radio occultation (RO) technique to study the physical properties of the Antarctic atmosphere.
The radio occultation (RO) technique sees electromagnetic signals refracted as they pass through the Earth’s atmosphere. Signals from GPS to Low Earth Orbit (LEO) satellites will be monitored as they pass through the atmosphere to reveal important atmospheric properties such as temperature, pressure, refractivity and relative humidity.
This information will be used in a feasibility study into the use of RO for meteorological and climate analyses over the Antarctic region.
This research aims to investigate long-term weather trends over the Antarctic region and the Southern Hemisphere by assimilating GPS RO measurements into existing NWP models. The limitations of the space-based Earth environmental sensing technique will be investigated and new methodology will be proposed. The methodology will enhance the accuracy and capability of this technique with the aim to improve the current weather prediction models and forecasting accuracy.
The objectives of this project include:
