Description An ICTP-IUGG Virtual meeting

The Workshop will discuss state-of-the-art, applications and perspectives of data assimilation and inverse problems in geophysical sciences. World leading scientists will be attracted to the program to present and discuss these topics in relation to specific geophysical disciplines.
 
Understanding the complex operation of the Earth system requires an interdisciplinary approach and international collaboration. Data assimilation and modern methods of solving inverse problems provide unique opportunities to exploit such approach and collaboration by integrating data and information from disciplinary sources. These techniques become major forecasting tools in meteorology, oceanography, atmospheric chemistry, hydrology, and recently they started to be applied to solid Earth problems. The workshop organized jointly by the International Union of Geodesy and Geophysics (IUGG), ICTP, and EAIFR will discuss applications of data assimilation and inverse problem methodologies to specific geophysical fields. The related scientific progress may contribute to the solutions of major societal challenges, such as climatic and environmental changes, disaster risk reduction, and sustainability. PhD students, postdocs, and advanced practitioners are encouraged to attend the workshop.
