7.4.2 Interpreting Graphical Ceiling / Visibility Reports
A graphical Metar report has three pages of information. The first
page of information shows Ceiling, Visibility and Precipitation for
each reporting airport. A vertical bar displays ceiling status and a
horizontal bar visibility status, forming an L-shape. The color of
the bar indicates the status.

7.4.4 Interpreting Metar Age
It is important to remember that METAR information from multiple
airports is not all from the same time period. The times of the
individual Metar reports is shown by color-coding the associated
airport identifier. Some airports don’t supply Metar data and have
normal coloring.
Identifier 0-30 minutes 30-60 minutes 60+ minutes
