UT Tartu Observatory, Marss Hall (Observatooriumi 1, Tõravere)


Professor Juhan Ross (1925-2002) was an Estonian atmospheric physicist at Tartu Observatory with a fundamental impact on the field of radiation transfer within and above plant canopies. With the year 2025 marking the centenary of Juhan Ross’ birth, this event will serve to celebrate Juhan Ross’ contributions and legacy.

The event will include distinguished invited speakers offering their perspectives on Juhan Ross as a scientist, colleague, supervisor, and family friend. The event is free of charge; everyone is welcome.

The invited speakers include:
Prof. Mart Saarma (President of the Estonian Academy of Sciences)
Prof. Agu Laisk (University of Tartu Professor emeritus)
Dr. Matti Mõttus (VTT Technical Research Centre of Finland)
Dr. Urmas Peterson (Tartu Observatory at the University of Tartu)
Dr. Tõnu Viik (Director of Tartu Observatory during 1985-1999)

The history of Estonian atmospheric physics and remote sensing likely begins with the moment when Juhan Ross, a recent graduate of the University of Tartu, was appointed as the head of the actinometry station at the Institute of Physics, Mathematics, and Mechanics in 1951. Under Juhan Ross’s leadership and broad scientific vision, the actinometry station quickly became one of the best in the Soviet Union at the time. In addition to high-quality routine measurements, efforts were made to improve measurement methodologies and instruments, as well as to formulate and solve scientific problems. In 1954, the station was renamed the Actinometry Laboratory, and in 1958, it became the Atmospheric Physics Division.
