What does the light mean?

The lights are used to quickly display the quality of the data to the user.

When the graphs are generated every hour, the data are also checked for missing or invalid values. The invalid and missing values are counted, and a reliability number for that graph is computed. The reliability number is then used to decide which color of light to display above the graph.

Light Color Reliability Represented

  • "Off" (grey) - No reliability data

  • Red - Less Than 65%

  • Yellow - Greater Than 65% but Less Than 85%

  • Green - Greater Than 85%
