Dear Phil,
Many thanks for keeping me updated on the PET work of Aiguo Dai and friends.
Also good to hear that Harry is nearing the end of his struggle with the updating. I'll
contact him to get the data, and then we can start doing some of the calculations.
One of my plans, next to analysing a scPDSI signal in the updated CRU data, is to see if it
is possible to build a European Drought Monitor - more-or-less similar to the US Drought
Monitor ( [1] ) - on the basis of the ECA&D
dataset. What do you think?
The ECA&D dataset is (in my opinion) a bit of a mess. The data is not updated frequently
enough and the numerics which should keep the data and the calculations of the indices
up-to-data are slow and cumbersome. Hopefully, this is sorted out before the new year
Cheers, Gerard

Kevin and Phil,
Attached is a paper (just submitted to GRL) on the effects of different PET
parameterizations on the simulated soil moisture and
PDSI over Australia and New Zealand. Tom Karl's group at NCDC is also interested in
looking at this in a bit more detail.

Just got this paper. I thought it might of interest. It is submitted to GRL.
Harry should have finished version 3 of the high-res dataset by the end of next week.
