Yes Stephen Salter has in some detail which he sent me recently. I could forward it to you but I would rather let Steven send it to you himself. What his modelling suggests to me is that careful placing of the ocean spray sites can go a long way to tuning world precipitation in areas remote from the spray site. Ocean spraying in conjunction with stratospheric aerosols should give us what is needed. Big project but I think we will have to do it. The met office also did some modelling to show that ocean spraying in a particular site would reduce rainfall in the Amazon and this was quoted as a negative in the first parliamentary committee hearing on geo but the met office witness failed to notice the obvious corollary to this bit of research. Namely that spraying in a different site would probably increase rainfall in the Amazon.

I note the quite reasonable concern below that the Amazon may dry and burn in a warmer world. This is based on Vizy et al., I assume. I am keen to know if anyone as modelled rainfall in an SRM world to see if the Amazon is critically dessicated under a mix of SRM and warming? We need to be sure that we get the right balance between cooling and drying. This may place limits on the SRM we could do, as it's unlikely to be viable to use SRM if it will cause Amazon collapse.
