Data access

Access to continuous data is available on several dedicated platforms, with access links provided below. However, for any requests regarding unavailable or more recent data, we invite you to submit a request via the contact form. The list of available data is described for each experiment: flux tower, partial rainfall exclusion, total rainfall exclusion, soil warming and rain exclusion, and thinning management.
