AB: When fully operational, the Transportable Array (TA) and Flexible Array (FA) components of the continent-scale EarthScope USArray seismic observatory project will provide telemetered real-time data from up to 600 stations. By the fifth year of the deployment the predicted total amount of data production for the TA and FA will be approximately 1500 Gb/yr and approximately 1000 Gb/yr respectively. In addition to delivering the data to the IRIS Data Management Center (DMC) for permanent archiving, the Array Network Facility (ANF) is charged with real-time data quality control, calibration, metadata storage and retrieval, network monitoring and local archiving. The Antelope real-time processing software provides the back-bone to this effort, supported by the Storage Resource Broker data replication/archiving system and the Nagios network monitoring tool. Real-time, web-based data mining, with support for multiple database schemas, is provided by an Antelope interface to both Perl and PHP scripting languages. This allows embedding of database functions in HTML. A suite of online tools allows query and graphical display of dynamic real-time sensor network parameters such as data latency, network topologies, and data return rates. Data and metadata are also web-accessible, for example XML trees of seismic data and graphical display of instrument response functions. The purpose of these tools is to provide the ANF, IRIS and end-users of USArray data with a real-time systematic method of determining data quality for the spatio-temporal area of interest. The tools are accessible at http://anf.ucsd.edu
