These archives can certainly have the EMULATE data - maybe you can have
them in a few months. I wouldn't want the gridded version to be available quite yet.
The station data should be up now.
IMPROVE is a problem. The co-ordinator (not me) signed an agreement with KLUWER
that the books would contain the data on CD. I'd just add the IMPROVE stations
to EMULATE and don't mention IMPROVE.
On NORDKLIM, best person to contact is Heikki Tuomenvirta <heikki.tuomenvirtaatXYZxyz.fi> .
On a website with a GCOS seal of approval. I don't see why not. I'd set one
up and discuss linking it from Geneva with Hans Teunisson
"Hans Teunissen" <HTeunissenatXYZxyz.int>
AOPC meets in Geneva April 11-15, so it would be good to have this to report. I'm
sure you've done much more !
Have a good festive break !

Dear Phil,
Rob and I have been having an email exchange about datasets that will be used for the
historical reanalysis project. We have also been having an exchange about making a
website for the AOPC/OOPC surface pressure working group.
To summarize the following:
1) Can NOAA NCDC and NCAR archive the input EMULATE, IMPROVE, etc stations that get used
in the reanalysis? Also, Rob specifically mentioned a NORDKLIM dataset, which I don't
have. do you have the details about accessing that and getting permission for archiving
2) What do we need to do to get a group website made "official" by GCOS?
What stage should it be in? From fully functional to preliminary plan? I will be working
with 2 people here to put together a website with at some of the functionality described
Your thoughts on both topics would be greatly appreciated.
Hope you have a merry Christmas and happy new year,
best wishes,

For the input datasets from EMULATE, I don't think that you have anything from 1938
onwards. Getting those datasets is really more important as we go back towards the start
of the 20th century. At the first EMULATE meeting at CRU, everyone there did agree that
I could get access to the datasets. That is why I can get to the website and am on the
mailing list. Luckily, I don't think that this will be issue because the timing will
be fine. Getting the data later next year. Should I/we correspond with Phil about the
details of making the data available for the historical reanalysis project?
As to the website, yes, it is really time to get going on that.
Here's a list of what the website might include:
1) Group business
Terms of Reference
Minutes from Previous Meetings/Workshops
2) Data access
A. Easy downloads of monthly and daily gridded SLP, surface pressure datasets:
Kaplan SLP
Northern Hemisphere SLP
NCEP Reanalysis SLP, surface pressure
ERA 40 Reanalysis SLP, surface pressure??
Otherwise, links to some and references for others?
B. Downloads of time series or links to the source
Madras SLP
4) Data analysis Tools like at
Even if we can't serve the data, maybe we can make it available for the Tools?
General questions-
How do we ensure that our site is an "official" GCOS site?
How do we get permission to place some of the datasets that you are involved with on the
I suggest that we send an improved version of this list out to the full group for
comment. What do you think?
Also, I will almost definitely be coming to the Oct meeting, so piggy backing a working
group meeting is a really good idea. Let's start planning that too. I think we can get
that in the workplan.

Sorry, I forgot that you were well linked to the EMULATE effort -
old age setting in.
I'm not sure if there are any stations which we got for EMULATE
that go through to the present that are not also ones you'd get from
WASA, NORDKLIM and the like. I'll check with Tara which ones go right
through in the EMULATE set.
With the longer historical reanalysis effort, it would be good to
touch base with Phil about that. I liked your suggested website layout
and sections, and I think we can at least come up with links to most of
them if not full downloads. It might be good to talk to Phil about how
we make it an official GCOS site, I don't know the politics of GCOS as
well as Phil does, and I think it would be a good step in sorting that
out. Again, re putting data sets on our site it will be a matter of
finding out what protocols they require. Once completed, EMULATE data
should be readily available, and others will be a matter of talking to
the right people. Over here in the UK, we have this Freedom of
Information act coming into place from 1 January 2005, and that may well
impact some things at this end re all of this.
I think that once we iterate a bit on the website outline you sent
and sort out a few of the other issues above we could certainly
circulate it to group members. Yes, we must start planning for the
meeting in October next year. For me, things are a little in limbo at
present as we wait to hear if our big proposal to the EC, AESOP, has got
through - a lot will be decided by the outcome of that project from this
end. So early in January lets iterate on the October effort - I am
hopeful we'll have heard one way or another about AESOP by then.
Hoping that you and your family have a really great Christmas and
New Year.
Cheers, Rob.
