ERCA 2017 teaching

Written by Jaša Čalogović on . Posted in News

thumb ERCA-201725th European Research Course on Atmospheres (ERCA) school was organized from 11th January to 9th February 2017 by Universite Joseph Fourier and CNRS in Grenoble, France. ERCA is a high level international course on the Physics and Chemistry of atmospheres, the climate system and climate change, atmospheric pollution at different scales and the human dimensions of environmental changes. The course also covers the solar influences on Earth's atmosphere and climate. This year, altogether 35 students were selected from all around the world to participate in ERCA. Jaša Čalogović was invited to give students two lectures ("Solar variability influences on the climate and cosmic ray - cloud link" and "A critical look at cosmic ray - cloud link: Forbush decreases and cloud cover"). Aim of lectures was to present the influences of solar activity on climate and the possible mechanisms linking solar activity with climate. The cosmic - ray hypothesis was also presented in detail with aim to show several potential problems in present and past studies analyzing geophysical data using correlations.

Festival of science 2016 in Hvar

Written by Jaša Čalogović on . Posted in News

thumb FZ2016 18From 21 to 23 April 2016 Festival of Science was organized at city hall in the town of Hvar, and this year's festival theme was "Science and Art". The event was organized by the Observatory Hvar and the Elementary School of Hvar, Stari Grad, Jelsa and the Archaeological Museum in Zagreb.

Science Festival is being held for the 14th consecutive year in Croatia and its goal is to bring the science to pupils of primary and secondary schools and the entire interested general public. This year, the Science Festival was organized in 18 cities in Croatia, and it was the second time that city of Hvar hosted it. Compared to the last year, organizers offered a much richer program and the Festival in Hvar lasted for three days, that was visited by students of almost all schools on the island (elementary school of Hvar, Stari Grad and Jelsa).
