CoopEUS sponsored a joint Carbon Data Users Workshop for early career scientists in southern France with the EU Integrated Carbon Observatory System (ICOS) and the National Ecological Observatory Network (NEON). The workshop not only centered on carbon and energy flux observations, and the surface micrometeorology surrounding these measurements, but also aimed at making data available that can be used without technical, scientific, cultural or political barrier in Europe, US and internationally. In addition, practical use cases and scientific hands-on approaches were explored that focused on emerging applications to use large-scale observations to ask regional-to-continental questions. We had a fully supported, very diverse group of 24 conducting science in17 different countries. World-renowned instructors came from the US and European countries.
