The deployment of Transportable Array stations for the Earthscope USArray project has begun and will ramp up to 400 real-time
telemetered stations over the next four years. The role of the Array Network Facility (ANF) in the USArray project is to
guarantee delivery of all Transportable Array stations (400) and telemetered Flexible Array stations (200) to the IRIS Data
Management Center, ensure proper calibration and metadata are always up to date, and provide quality control for all data.
In support of these goals, we use the Antelope software package to facilitate data collection and transfer, generation and
merging of the metadata, monitoring of dataloggers, generation of noise spectra, and analyst review of individual events.
The SRB, and a newly developed Antelope/SRB interface, is used for off-site backup of the data. A freeware package, Nagios,
adapted to include Antelope plug-ins, as well as newly developed in-house tools allow network and data flow monitoring.
Quality control checks include: daily review by an analyst to look for obvious discrepancies in channel polarization or
change in noise characteristics; associations made against regional network and global bulletins to help spot timing errors;
spectral noise plots; and daily reports of outages and data gaps.
