So with the water cycle intensity WCI = P + AET, (eq 4) where P is precipitation and AET the "actual evapotranspiration". What variables are usually available to compute AET?
Eq. 1 says : P = AET + Q + dS/dt, so I guess: WCI = 2P + Q + dS/dt, but are Q and dS/dt available in models?

I think Q + dS/dt would be given by mrro (https://pcmdi.llnl.gov/mips/cmip3/variableList.html)

Note that this is a low priority task. I just noted it as I thought it would be interesting to look into for model diagnostics.
