Fred,
Sorry to have bothered you when you're away.
Walter and Allan, would you like me to provide some specific examples?

Wayne and Linda,
Wayne is correct we receive Canadian SA data in both METAR and AIRWAYs
formats. both are made available in their native format and the
Canadian Airways reports along with a few remaining U.S. reports in
AIRWAYs code are converted to METAR here at the NWSTG. We are aware of
some translation problems which have been corrected. I'm not completely
sure if all the problems we were aware of fixed. It is also possible
Wayne has identified a different problem.
Wayne should pass the details to Walter Smith and Allan Darling.
Allan's branch is responsible for the software and Walter for Data
Management.
Sorry I didn't get back to you sooner but I'm out of the office.
Cheers, Fred

Hi Wayne,
FYI-Joe Irwin's email bounced. I believe he retired and I forgot
about that, so we'll hope that Fred will get back to you on this
question.
Thanks again,
Linda

Linda,
That is a good question. If issued by the CWAO office, then the
format is standard airways (SA) and the precipitation is correct.
If issued by KWBC, then the format is METAR and the precipitation is
incorrect. As another check, the METAR format can't be correct as
the monthly precipitation totals for many of the Canadian sites
starting in April 2006 are very low (2-11 mm) and those values are
not realistic.
Thanks for tending to this quickly.
Wayne

Hi Wayne,
I've copied two people at the NWS, but when I read your email, I
wondered if this is happening on the Canadian side or at the
NWSTG. In any event, hopefully either Fred or Joe will get back to
you.
Thanks!

Linda,
Good morning.
Recently I was looking at some Canadian surface data that we
receive via LDM. Apparently it is received in both SA (standard
airways) amd METAR format. Correct me if I'm wrong, but the SA
data is converted to METAR format at the NWSTG and retransmitted.
In that process, precipitation is not being converted correctly.
Do you know the appropriate contact at the NWS that would be
responsible for the conversion process? I'd like to start a
dialogue and see if the problem can be fixed.
Sincerely,
Wayne
