Alan,
Thanks. I thought it might be something like you've found. They are supposed to produce
CLIMAT monthly summaries. The 6 hr messages are called SYNOPs. If someone is keen
down there to improve things they could contact either Tom Peterson at NCDC or
Howard Diamond at NOAA HQ. Howard is the US's focal point for all GCOS activities in the
US. Both report to Tom Karl.
"Thomas C Peterson" <Thomas.C.PetersonatXYZxyza.gov>
Howard Diamond <Howard.DiamondatXYZxyza.gov>
Any changes to US stations in the GSN or the GUAN get done by Howard.
The problems you allude to - contractors taking the measurements (probably also at the
South Pole) is also the case in some parts of the Middle East and also some U/A sites in
Africa and South America. The ascents are all done by contractors and not the Met Service
in some countries and it isn't in the spec to produce CLIMAT or CLIMAT TEMP (the monthly
summary of the ascents) messages.
Howard will be aware of a software package that a WMO contractor has produced for
distribution to countries to produce monthly CLIMAT messages from the SYNOPs.
Hope you're still enjoying the experience down there !
Cheers
Phil

Dear Phil,
I went and had a talk with the weather folks here. They produce the
standard 6 hr CLIMAT messages and send them over the GTS to Asheville
regularly. They do not produce monthly summaries. So the data should
be in the Asheville records, and you can calculate the means from them.
They do not calculate daily means or monthly means here.
There are no records here of past data. When the private contractors
took over from the Navy in 1996, the room with all the Navy records was
emptied and sent to trash. Apparetnly there were no climatolgists on
the transfer team!
Sorry I could not give you better news.
