[wxqc] MADIS explanation needed

[webmaster]

Gerry,

It would be nice if we could get an official response from the 
programmers.  It isn't my station that has the two thumbs up and a 
big red X, it is the local AWOS station.

I thought the thumbs up or down rating were affiliated with the 
symbol above them, apparently not.

It would be nice if there was some documentation (and maybe there is) 
that explains what the symbol on the top is and how it differs from 
the thumbs below.  In my mind a big red X is like getting an "F".  My 
teachers never wrote in "RED" unless you flunked...so it seems like 
an oxymoron to have a big red X AND two thumbs up.  So apparently the 
big red X is the rating of something different than the two thumbs up 
below that???  I don't know why there are two ratings for one item 
and how the results could be so different.  the AWOS site is the only 
site where I have seen the big red X.  They also have a yellow 
question mark on another item and I haven't seen that before either.

Thanks,

Lew
