==ALMA regional centre (ARC)==
The ALMA regional centre (ARC) has been designed as an interface between user communities of the major contributors of the ALMA project and the JAO. Activates for operating the ARC have also divided into the three main regions involved (Europe, North America and East Asia). The European ARC (led by [[European Southern Observatory|ESO]]) has been further subdivided into ARC-nodes<ref>{{cite web|url=http://www.eso.org/sci/facilities/alma/arc/nodes|title=ARC-nodes|author=webteam@eso.org|access-date=15 November 2014}}</ref> located across Europe in Bonn-Bochum-Cologne, Bologna, Ondřejov, [[Onsala Space Observatory|Onsala]], [[Institut de Radio Astronomie Millimétrique|IRAM]] (Grenoble), Leiden and [[Jodrell Bank Centre for Astrophysics|JBCA]] (Manchester).

The core purpose of the ARC is to assist the user community with the preparation of observing proposals, ensure observing programs meet their scientific goals efficiently, run a help-desk for submitting proposals and observing programs, delivering the data to principal investigators, maintenance of the ALMA data archive, assistance with the calibration of data and providing user feedback.<ref>{{cite web|url=http://www.eso.org/sci/facilities/alma/arc|title=ALMA regional centre|author=webteam@eso.org|access-date=15 November 2014}}</ref>
