European ALMA Regional Centre


The European ALMA Regional Centre (ARC) provides the interface between the ALMA project and the European science community. It supports its users mainly in the areas of proposal preparation, observation preparation, data reduction, and data analysis.

Unlike its partner ARCs in North America and Japan, the European ARC is organized as a coordinated network of scientific support nodes distributed across Europe. The central node is located at ESO Headquarters in Garching bei München and carries the responsibility for all the core ARC activities as well as the coordination of the additional science support provided by the regional nodes and centres of expertise.

The European ARC is the point of contact for European ALMA users from the moment of proposal submission to the actual distribution of calibrated data and subsequent analysis via the ALMA Helpdesk.

Funding for face-to-face support at one the European ALMA Regional Centre nodes is available for ALMA Users. Users wishing to apply for MARCUs funding should fill out the form, in addition to submitting a ALMA Helpdesk ticket.
