Most of the 'SA' that I have looked at appear to be part of an
agricultural network in the Canadian heartland.
For gempak users, dcmetr handles these fine also.

Daryl,
The SA code was the precursor to METAR. SA stands for Surface Airways I believe. Why the Canadians are so insistent
about continuing to output data in this outdated format, I can't say. The old WXP decoder "sacvt" can decode this format.

Greetings,
In today's adventure of curiousity killing the cat, I wonder about the
following product:
SACN90 CWAO 151600 RRA
WFF SA 1600 AUTO8 M M M 087/18/14/1813+19/M/ PK WND 1920 1510Z 3004
90MM=
WFP SA 1600 AUTO8 M M M 128/10/09/0902/M/0008 2009 86MM=
So for the TTAAII header of "SACN90", it seems that the usage of 'SA'
should dictate FM 15 (METAR) format as per:
http://www.wmo.int/pages/prog/www/ois/Operational_Information/Publications/WMO_386/AHLsymbols/TableB1.html
<http://www.wmo.int/pages/prog/www/ois/Operational_Information/Publications/WMO_386/AHLsymbols/TableB1.html>
Is this "SA" format some variation on METAR documented somewhere or is the
WMO header just wrong for this product?
thanks for educating me!
daryl
