Regional OBIS Nodes (RONs) are organizations that have committed to a continued support of OBIS within a geographic and/or national region using resources they have obtained. This includes serving data online and developing a data provider and end-user community. Some RONs provide tools, different language versions of the OBIS website, and/or provide mirror sites for the OBIS portal.
