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]http://www.drought.unl.edu/dm/monitor.html ) - 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 starts.

Tom Karl's group at NCDC is also interested in looking at this in a bit more detail. Aiguo Kevin Trenberth wrote: FYI Kevin Gerard, 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.
