METAR is a format for reporting weather information, and its the format that pilots consume while flight planning or en-route.  Most larger airports have their own weather station and distribute METARs concerning the weather at their location.  A METAR map uses a small micro-controller to download METAR information from those airports and display it on a map using colored LEDs.  For example, green for good weather, red for bad, and other colors in-between.

The small LEDs change color based on the weather in that area.  This map displays weather in 13 locations across the map.
