QAT MissionQAT MissionQAT MissionQAT Mission

Document current waveform quality on a station-by-station

basis

Review and correct, as necessary, metadata for all stations

Identify sources of waveform quality problems (sensors, sites,

systems)

Review historical data to document and correct problems with

metadata

Assess current practices, policies and procedures

Develop metrics and procedures for routine quality

assessment

Establish reporting mechanisms to communicate data quality

Technical Approaches of the QAT are sound

GSN station certification is required

Standardization of QC practices across GSN

Metrics must feed into a management process

Communications with User community

Publicly available QC monitor

Remediation plans on line

two-way communication (feedback)

For this meetingFor this meetingFor this meetingFor this meetingReports from USGS, IDA, and DMC on QA initiatives underway

What tools under development have pan-IRIS/USGS applications?

Concepts of coordinated QA Implementation

How can we best coordinate our efforts and share implementation?

Some redundancies necessary, but how can we optimize?

How can we share this across all IRIS programs?

How do we move forward and continue this exchange?
