This paper presents an overview of the Australian Coastal Ocean Radar Network (ACORN), part of the Australian Integrated Marine Observing System (IMOS. ACORN currently operates 12 radars in 6 dual radar pairs at sites around the coast of Australia. Some of the issues associated with operating multiple radar systems with different technical requirements, often sited in remote areas, are discussed. The availability of data depends on the robustness of the radar systems, the level of external interference and the ability to respond quickly to hardware and software issues that may arise. Some validations of the data obtained will be presented
