The change factors are not available yet because of the slow run time of the RCM being run specifically aimed at emulating the heat island effect. Consequently my initial runs will be for the control period to conduct some sensitivity analysis and make comparisons with what little obs data we have. "We have resolved the "crap parameter" problem" - good that means the likes of Aldergrove will now run OK(?), could you send me the latest executable to run with the stand alone please. Actually I was referring to the earwig cumulative predictor variable problem I came across, email of 28/05/08 reproduced here: If you select more than one run then: First run and the following predictors are passed (Ringway cell, these look sensible): 382500 382500 72 68 2nd 765000 765000 144 136 3rd 1147500 1147500 216 204 10th 3442500 3442500 648 612 Spot the pattern? It is accumulating the original predictor values each time. By the 3^rd run the cru wgen keels over. I think I have the latest version of earwig, the setup exe is v2_1.

Can you define exactly what change factors/cells are needed? We have resolved the "crap parameter" problem: a new fitting procedure implemented, and we can now plot maps of how good the fits are (final values of objective function).

My problem is generating the precip since I will not be able to use the stand alone rainsim version. I could do some initial daily control runs using earwig, however there is the problem I mentioned in my email of 28 May - has this been resolved? Also when I manually select more than a few individual cells the GUI crashes - just disappears from the screen. Ideally a stand alone UKCIP08 version that perhaps just takes the grid coordinates and change factors as arguments, (i.e. no graphical interface) would do the trick (I would then be able to set up a batch run). Can the core wgen be easily isolated? Cheers Colin
