AB: Over the past three years the Array Network Facility (ANF) has developed a robust, extensible web-based toolkit for monitoring the state-of-health of Earthscope's Transportable Array. The tools are constructed within a framework of the Antelope Real Time System (ARTS) and the Antelope interface to the PHP Hypertext Processor (PHP), an inline scripting language. Exporting data from Datascope databases and Object Ring Buffer (ORB) packets into XML allows comprehensive client-side interaction via Asynchronous Javascript And XML (AJAX) calls. Navigating and displaying the resultant XML Document Object Model (DOM) trees are done using eXtensible Stylesheet Language Transformation (XSLT) and PHP's built-in DOM classes. Tools include regional and individual station and event maps, state-of-health statistics, waveform plots, and datalogger monitoring. Combined with real-time graphing of state-of-health parameters from status ORB packets using Round Robin Database Tool (RRDtool), this toolkit allows analysts, station engineers, scientists, and the general public to view, assess, interact with, and download data collected from the 250+ stations in the Transportable Array seismic network. Tools are available at the Array Network Facility website, http:anf.ucsd.edu.
