Hvar Observatory

Hvar Observatory (OH) is a department of the Faculty of Geodesy, University of Zagreb (UNIZG), devoted to scientific research of stellar and solar physics and space weather. The Solar Department of OH is involved primarily in observational and theoretical research on eruptive phenomena in the solar atmosphere (CMEs, flares, coronal shocks), interplanetary propagation and geo-effectiveness of CMEs and SIRs, as well as their influence on cosmic rays. The group is experienced in both analytical modelling and observation of short-term FDs, and is the prime developer of the analytical diffusion-expansion Forbush decrease model ForbMod. The group also has extensive experience in both remote sensing and in-situ observations of CMEs and SIRs, as well as both theoretical and observational analysis of their evolution. The group is the prime developer of the drag-based model (DBM) for heliospheric propagation of CMEs and a co-developer of the empirical solar wind forecast (ESWF) tool. Dr Mateja Dumbovic will be the main person responsible for carrying out the proposed research at OH. Her primary interest is in solar and heliospheric physics and space weather, particularly propagation of CMEs and their space weather effects, especially Forbush decreases. She has extensive knowledge in both observation and analytical modelling of Forbush decreases and has developed an analytical diffusion-expansion Forbush decrease model ForbMod. She is the holder of several national and international awards and fellowships. Dr. Dumbovic will be involved in WP5 and WP7, leading a task in both WPs.
