Quality Assurance

The Oklahoma Mesonet’s quality-assurance (QA) consists of four principal components:

1. laboratory calibration, 
2. on-site intercomparison, 
3. automated QA, and 
4. manual QA.

In the instrument laboratory, all sensors are calibrated to validate or improve upon factory calibrations.

On an annual basis, the accuracy of several types of sensors in the field is verified through comparison to calibrated reference sensors housed in a portable system.

To make a first pass through the over 640,000 observations that are received at the Mesonet each day, automated QA software includes numerous algorithms to evaluate the data received from remote stations.

Finally, the Mesonet’s QA meteorologists employ numerous manual techniques to complement automated QA including analysis of monthly statistics to detect sensor drift or bias. In addition to detecting problematic sensors, the QA meteorologists trace the true start time of each problem so that appropriate data can be manually flagged as erroneous. The QA meteorologists are responsible for communicating problems to, and coordinating with, appropriate field technicians to ensure proper resolution.
