What is the difference between metar and aaxx???

Hello,
when reading weather information from www.wunderground.com, sometimes
it's derived from metar which is relatively simple to understand and it's
many descriptions of it on the Net. But other times it's derived from a
terrible messages that begin by "aaxx" and following five nothing-saying
numbers. I would like to ask somebody who knows, what is aaxx message and
where to find a description of it.
Thank yiou.
Adam
