Research Themes (RT) and Aims

this subpage is available in English only


RT#1-GNSS1) radio occultation for climate monitoring, diagnostics, and processes

1. establish benchmark-quality GNSS radio occultation records of GCOS (Global Climate Observing System) essential climate variables of the atmosphere, such as temperature and water vapor, and use them for ground-breaking climate diagnostics and processes studies

2. establish the WEGC as host of the Earth Observation Processing for Atmosphere and Climate (EOPAC) center, tasked to act as a leading European Center for climate monitoring and benchmark reference data provision based on GNSS radio occultation

3. sustain and advance the WEGC Occultation and Climate Analysis System (WOCAS) - consisting of EGOPS2), rOPS3), and post-processing and data provision systems - which is the core system for implementing novel algorithms and achieving goals 1 and 2

1) Global Navigation Satellite System, 2) End-to-end Generic Occultation Performance Simulation and Processing System, 3) Reference Occultation Processing System


RT#2-Climate and hydrology change monitoring and analysis at regional-local scale

1. perform frontier research on climate-hydrology change to understand processes that govern regional and local variability and changes in the European Alpine region, with focus on analyzing hydrological extremes (heavy precipitation, droughts) in a warming climate

2. exploit the unique WegenerNet datasets with their 1-km scale resolution for studies such as evaluating convection-permitting climate models, validating satellite and ground radar data, and exploring properties of heavy precipitation at very high resolution

3. maintain and enhance the WegenerNet climate station networks Feldbach region and Johnsbachtal, managed and operated by WEGC, as internationally recognized and utilized field facilities for high-resolution monitoring, validation, and model evaluation


RT#3-Support next-generation global observing system for monitoring the climate

1. support ACCURATE1) climate mission concepts and projects, conceived for accurate global observation of thermodynamics, clouds, wind, and greenhouse gases by low Earth orbit occultations and complementary techniques, towards mission implementation and use for climate monitoring and research

1) ACCURATE—climate benchmark observation of thermodynamic variables, clouds, wind, and greenhouse gases from space
