Tomislav Žic participated at NASA 8th Community Coordinated Modeling Center (CCMC) workshop in USA, where he gave an invited talk "The drag-based model" and participated in a discussion regarding current status, plans and future collaboration with CCMC.

22-26. February 2016 an international scientific workshop was held at the Kanzelhohe Observatory with participants from the Physics institute of the University of Graz, Institute for extraterrestrial physics of the University of Kiel and Hvar Observatory of the University of Zagreb (B. Vršnak, J. Čalogović and M. Dumbović). The workshop addressed important aspects of solar physics and space weather related subjects such as coronal mass ejections, coronal waves, solar energetic particles and galactic cosmic ray modulation (Forbush decreases). Participants presented their most recent research results leading to a number of scientific discussions and plans for future collaboration.

From 5. to 19. February 2016 Jaša Čalogović visited Dr. Benjamin Laken at the Department of Geophysics, University of Oslo. The aim was to work on current research topics (eg. regional influences of cosmic rays on certain types of clouds), develop future research plans and strengthen the collaboration. During the stay J. Čalogović also gave a talk "A critical look at cosmic ray-cloud relationships" at Department of Geophysics. 

24th European Research Course on Atmospheres (ERCA) was organized from 6. January to 4. February 2016. 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. More than 35 students from all around the world participated ERCA.
Jaša Čalogović was invited to give students two lectures ("A cosmic ray - cloud link and cloud observations" and "Composite analysis and Monte Carlo methods - an example with Forbush decreases and cloud cover"). Aim of lectures was to show effects of space weather on Earth, present cosmic - ray hypothesis and show potential problems that were present in past studies analyzing geophysical data.

1-5. February 2016 M. Dumbović visited the Udaipur Solar Observatory (USO) of the Physical Research Laboratory (PRL) under the Department of Space in India. Several meetings were held with Dr. Nandita Srivastava regarding the future collaboration on Space Weather research, and the USO staff members presented and described the USO scientific instruments. M. Dumbović held a seminar titled “Space Weather research at the Hvar Observatory ” for the staff members and students.
