This following paper is published in ACP today. The main focus is on the hydrological impacts of varying the latitudinal distribution of a FIXED amount of aerosols. Sensitivity of simulated climate to latitudinal distribution of solar insolation reduction in solar radiation management A. Modak

Dear Michael, Dear All, Our proposal concerns mainly current tropospheric anthropogenic sulfate emissions. Global man made annual SO2 emissions were 143 Tg SO*2* in 2008 (Huneeus, N. 2013), and the radiative forcing due to sulphate aerosols is estimated to be −0.4 W/m2*. * Incidentally, we

2014-08-05 Thread Alan Robock
Dear Mike, I don't understand this suggestion. Because of the shorter sulfate lifetime than in the stratosphere (even if it is more than the 1 week you get for surface injections), you would require a much larger sulfur injection for the same radiative forcing as compared to the

Hi Alan (and others as I had another query on this as well)‹Indeed, a bit more explanation of the suggestion is warranted‹so a few thoughts and quick reactions, not necessarily fine tuned: First, the SO2 would not be emitted from existing sources‹the idea is to separate the sulfate layer from

Better perhaps to adjust bunker fuel sulphur. Jason Blackstock (cc) did some excellent work on this, which I don't think got published. Presently the trend is for desulphurisation of marine bunker fuel, giving perfectly sensible port air quality improvements. This is, I understand, now the

Research could look at that, but the approach I propose would put the SO2 above the boundary layer, which would let it spread more broadly, lead to a longer lifetime, and why limit one¹s coverage so much to shipping lanes? It seems to me that the bunker fuel suggestion is closer to what the cloud

Seems to me that for stack injection above the boundary layer you are going to need a hot plume or a very tall stack indeed. Have you done calculations of the materials and energy requirements for a sufficient number of stacks with thermally buoyant plumes? Sent from my iPad On Aug 5, 2014,

Ken cc list This is to support your request for ideas for a #2 list (though I wonder what is on the #1 list). I recognize that you asked for only in the SRM category, but Andrew added two (his 7th and 8th) on CDR (which probably sound to a few CDR-folk as not so myth like) so I
