I detect a research project in your future. Drag out your spreadsheet.

I suspect one of the Kamchatka Peninsula volcanos?? Very remote area with big volcanos 🤔

I would like to compare against punytubo.

What is also interesting with volcanoes is that a ten times as large volcanic eruption does not necessarily cool ten times as much. So while climatologists are probably focusing on the effects of super big VEI 7 and 8 eruptions, ice ages might be set off by a series of large VEI 5/small VEI 6 eruptions spaced neatly together. If such type of eruption takes place approx every 25 years and at random it would mean that you get a decade with three of them every 1730 years, 4 of them every 23700 years and 5 of them every 475000 years. Together it might not register all that much in the ice cores but it would look like a much more smoothed distribution over an entire decade or more.

Does the size of the eruption have anything to do with height plume reaches into atmosphere?? Wouldn't this be critical to have a climatic effect. Volcanic discharge in the troposphere probably gets returned to surface via precipitation quite readily?

Volcanic discharge in the troposphere probably gets returned to surface via precipitation quite readily? There is probably a cross over point. A volcano in the Antarctic or Arctic in their winter when the tropopause is a LOT closer to the surface need not be as powerful as a volcano near the equator where the tropopause could be 70,000ft on occasions but at the same time there is less effect on solar radiation at the poles. The other issue apart from size is gaseous and aerosol make up. An eruption that is high in sulfates may have more effect than one that is just lobbing ash. Then of course if you get a persistent eruption (Siberian Traps for example - 2,000,000years !! ) then all bets are off

Probably not. Time is a factor.

Raikoke explosion seems to have put over 1 TG of SO2 into the atmosphere. Largest explosion in years I believe.
