Ogimet has developed an annoying habit lately of omitting 6-groups

because, if so, it will be screwing up my Scottish rainfall records..
UKMO say the synops they broadcast have all the 6-groups intact. I
clicked on Ogimet’s “Contact” button and sent them a complaint, but
just got a non-delivery message Still, I suppose what you don’t pay for
you can hardly complain about, as my sensible wife says.

Hi Ian,
The full SYNOPs, including the 6-groups, can be found at
http://weather.cod.edu/digatmos/syn/
Not quite as user-friendly as OGIMET as there's a separate file for each
hour. Nevertheless, the info is all there.
Incidentally, the Kirkwall 6-groups at 0000z and 0600z yesterday were 6///1
and 6///2 respectively.

Don't forget Florida State University either where I used to get my SYNOP
data till OGIMET came along.

Interestingly the rainfall at Kirkwall was a trace at 1800 UTC.

and at 0000 UTC zero.

There seems to be something odd going on here.

Not sure what point you're making here, Bruce. The rainfall reported at 1800 is
for the 12 hours 0600-1800 while the rainfall reported at 0000 is for the 6
hours 1800-0000. There's no inconsistency between the two figures reported.

Sorry, I mistakenly thought that you were talking about the 0000 on the 8th and not the 7th. You're right about the Kirkwall observation for the 07-0000 it did omit the rainfall total.

And by the way, I have done enough observations in my time to know that the rainfall group in the SYNOP for midnight was for a six hour period.
