A Method of Quality Control for Systems that Quality Control Data

February 28, 2005NOAA / NOS / CO-OPS

System Quality Control

February 28, 2005NOAA / NOS / CO-OPS

A Classic Example

February 28, 2005NOAA / NOS / CO-OPS

National Current Observation Program

Provide Data for:• Navigation• Search and Rescue/HAZMAT• Coastal & Estuarine Circulation

Tidal Current Tables

Tidal Current Predictions from:– Area Surveys– Real Time in Shipping Channels

Why?• Increasing data flow

– Yearly increase in the number of data collection sites

– Increasing temporal resolution

– Increasing spatial resolution

• Collaboration

– Distributed Data Sets

– Various Numerical Units

– Various File Formats

• Antiquated Computer Software
