Next year, the Ruisdael Science Day will be incorporated in the NAC Conference for the first time. The NAC Conference brings together all fields of research within the Earth Sciences and aims to provide an interdisciplinary forum for discussion and for researchers to present their work and results. The programme will consist of plenary sessions with invited (inter)national keynote speakers, parallel sessions dedicated to oral presentations and poster sessions. Ruisdael will play a prominent role during the Conference and all disciplines involved (instrumentalists, data analysts and modellers) will present their work. The NAC Conference, and therefore the Ruisdael Science Day, will take place on 12 and 13 March 2020 in Utrecht, the Netherlands. Please save the date!
