Theme #1: Atmospheric and oceanic processes in coastal regions

This research work of the Environmental Physics Group is based on observations, analyses and modeling of atmospheric and oceanic processes at different time and climatic scales. In particular, coastal climate and projections of future climate are studied using high-resolution regional climate models.  The studies are carried out within the activities of the STIM Excellence Center, supported by the Croatian Science Foundation, within the projects of the Faculty of Science in Split, and within the projects implemented in cooperation with the Institute of Oceanography and Fisheries in Split. Cooperation has also been established with the Universities of Bremen (Germany), Lesvos (Greece) and the Institute of Meteorology in Belgrade.

Theme #2: Atmospheric and ocean pollution in coastal regions

Methods for monitoring and forecasting coastal water pollution in current and future climates are being developed using ground-based meteorological measurements, remote sensing, and unmanned aerial vehicles.  The work includes modeling studies based on Lagrangian stochastic models in a complex atmosphere-sea medium in coastal regions. These research studies are carried out within the activities of the STIM Excellence Center, Croatian Ministry of Science and Education, within the projects of the Faculty of Science in Split, within the projects in cooperation with the Institute of Oceanography and Fisheries in Split, and collaborators in Chile.

Theme #3: Clouds and fog

The influence of urban environments, clouds, and fog on the modification of atmospheric parameters is carried out by data analyses and numerical simulations in conjunction with collaborators from the US, China and Serbia. Correlation studies of short-period climate variations with changes in coastal climate parameters are studied by deterministic and probabilistic forecasts.

Theme #4: Ocean primary production modelling

Primary production modelling refers to bio-optical models of carbon assimilation in phytoplankton photosynthesis, with a strong focus on coupling the physiological status of phytoplankton populations to environmental variables. This coupling is well established with respect to the light control of photosynthesis, both in experimental and filed conditions, along with a deeper theoretical understanding of the photosynthesis-light relation. Research carried out in this filed by the Environmental Physics Group focuses on further development of analytical bio-optical models of photosynthesis and their coupling to more complex ocean ecosystem models. A strong focus is placed on model verification and data assimilation. The research is carried out in cooperation with colleagues from the United Kingdom and the United States of America, as well as with the Institute of Oceanography and Fisheries from Split.
