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

yesterday (the 7th). I’m wondering if I’m missing rainfall
thereby 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.

03017 15683 /0410 10052 20006 30143 40176 56003 69902 333 10067
55300 20000 87/48=

and at 0000 UTC zero.

03017 15681 /2502 10038 21016 30118 40151 58017 60001 333 55///
20120 88/49=

There seems to be something odd going on here.

Bruce.

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.

03017 17781 /0313 10061 20018 30161 40193 51005 6///1 723// 333
55/// 20250 87/50 90710 91130=

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.

Bruce.

I had guessed that we were probably talking at cross purposes!
