The Federated Earth System Simulation and Data Processing Platform (FedEarthData) can be accessed through the following access policies:
Policy-based access: Users are granted access based on policies defined by the C-SCALE project or by the individual providers of the service; such policies usually apply to resources being offered with "sponsored use" to meet some national or EU level objective; for instance, a country may offer resources with sponsored use to support national researchers involved in international collaborations.
Market-driven access: Users can negotiate a fee to access the service directly with the resource providers.
All access policies may not be available for each and every provider or scientific data set.
