| Abstract | The proliferation of HF radar networks around the globe has made them a vital component of the ocean observing endeavor. There are approximately thirty-four nations with oceanographic HF radar networks, eight of which have over 10 radar stations in their network. Providing high quality measurements for sustained periods of time is of the utmost importance. The global HF radar network has been established to meet this goal. The network was established in 2012 with the goal of increasing the number of coastal radars, develop emerging applications of the data and to deliver a set of easy to use standard products. The network was established under the Group on Earth Observations (GEO) work plan for 2012-2015. The work plan endorses a task to plan a Global HF Radar Network for data sharing and data delivery and to promote the proliferation of HF radar surface current velocity measurements. The goal of this paper is to propose quality standards for this global network. In this paper we will take inventory of the existing quality assurance and quality control measures that have been proposed at the radial level and offer measures to manage the systems on a network level. We have developed a best practices checklist for validating and operating a HF radar stations in the Mid Atlantic - a checklist that can be transferred to other regions nationally and internationally. Some of these techniques include the comparison of radials from measured and ideal beam patterns. We have also performed beam pattern sensitivity tests, first order line settings tests, angular segmentation tests and different time averaging schemes on the radial data. We share the results of those tests here so that they may be replicated by other operators to strengthen the methodology. We propose best practices for the operation of a High Frequency radar network. The techniques outlined in this paper have shown an increased accuracy of the measured radial currents and a better understanding of the data processing stream associated with the particular HF radar system. The other networks around the globe can adopt the methods and best practices outlined in this paper. The other networks can also provide input to these methods and best practices which will result in an improved surface current measurement. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
