The P time series I looked at were country means and probably the spatial averaging hid the
spikes enough that they weren't such outliers. For T, you may remember that I did find
results like that for some countries (Bolivia was one, I think) which probably matches this
location and timing. So, yes, we did know about that.
The P and T anomalies found here are pre-1950. So for QUEST they are unimportant and thus
investigation cannot interrupt QUEST at this stage. But later on we can get back to
pre-1950 problems with CRU TS and hopefully solve them.

Hi Tim,
Please can you have a quick look at the attached doc? Did your
assessment of CRU TS3.0 T and P show these spikes, I can't remember?
Cheers
Harry

H,
This came from Jureg. Phil was not sure that Juerg has the latest
versions of the grids. I thought that he may have. I made the
grids available to Juerg on 01/05/08 (but I have deleted the files
from the ftp disk). Were there any changes to temp. and precip.
after that date.
Cheers
David

Dear Phil and David
I hope you are very well.
First of all thanks very much for your offer using the new gridded
0.5x0.5 CRU
TT and prec data. That is great and we already started using them.
Please find attached a short docu where we have tried to bring up
some features
we have found related to south american temperature. Maybe Phil, we
will have
some time talking about them
next week in Zuerich?
best wishes and have a good weekend
Juerg
