“…After numerous computer simulations, it was found that the overpressure in the gas cap just prior to impact corresponding to MC, -5 x lOI g can best explain the flattened forest associated with this event for the zenith angles considered. This is in good agreement with existing estimates for A&, (Fesenkov, 1966 ; Turco et al, 1982). In solving these equations, it was found that the nuclear energy released during the comet's -3 s passage through the atmosphere was indeed negligible.…”

“…This discrepancy is probably because part of the nitrogen may have been injected into the upper atmosphere and distributed over a large area of the Earth. However, the quantity of NO produced during the Tunguska event, estimated by Rasmussen and his colleagues, is a factor of 50 lower than that calculated by Turco et al (1982). Figure 4 shows the results of carbon analyses in the KEM N21 peat column.…”

“…This event has been the subject of debate regarding several aspects, including the nature of the bolide -a low-density cometary body or stony meteorite. In the first case, accompanying the progressive ablation of the body during its entrance into the atmosphere, thermal decomposition of N 2 and O 2 would have efficiently produced NO through the mesosphere and stratosphere (Turco et al, 1982). Estimation of the production reached 30 Tg of NO and would be detected as enhanced nitrate levels in snow deposited in both Greenland and Antarctica during at least one year.…”
