During March 8-10th 2016, the Monitoring Station Assembly of the ICOS Atmospheric Thematic Centre (https://icos-atc.lsce.ipsl.fr/) will meet in Brno. The meeting will host 65 international scientists and focus on organizational as well as scientific and technical progress within the atmospheric part of the ICOS network. Some visitors will also take part in a field trip to the Atmospheric Station Křešín u Pacova, which is just about stepping into the labelling process to become an ICOS Class 1 site.
