The power unit would work like a jet at slow speeds in the lower atmosphere but then transition to full rocket mode at high speed in the upper atmosphere to make the jump to orbit.
The team's calculations estimate the quantities ejected upwards at high speed into the upper atmosphere included 325 gigatonnes of sulphur (give or take 130Gt) and perhaps 425Gt of carbon dioxide (plus or minus 160Gt).
The craft plunged into the upper atmosphere at a speed of 12,000 miles an hour.
The next graphic shows what happened at jet-stream level in the upper atmosphere.
In fact we believe these waves were originated from the middle atmosphere [about 50 kilometers] but we observed them in the upper atmosphere at approximately 300 kilometers.
It is becoming less of a stream and is behaving more like a sluggish estuary that is meandering across the upper atmosphere at middle latitudes".
Practically, he says, this proposal would involve commercial jetliners pumping sulfur into the upper atmosphere, at a very small cost to the global community.
The hole, actually a broad region of reduced ozone levels, occurs when Freon and similar synthetic chemicals, in concert with frigid air and ice clouds in the upper atmosphere at the poles, destroy ozone molecules.
They note that despite the warming at and near the surface, the upper atmosphere has cooled, ruling out the Sun as the cause.
Shorter AGWs with smaller horizontal wave speeds produce smaller mean heating and wave-induced mean velocities in the upper atmosphere at fixed amplitudes and periods of the surface wave excitation.
