   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

     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
