Lightning bolts appear to be able to produce neutrons by processes associated with the acceleration of ions to an amount estimated to be about a percent of the cosmic ray neutron production. The corresponding effect on radiocarbon in tree rings can explain the well‐known short‐term secular errors in radiocarbon dates as being caused by climatological fluctuations in frequency of lightning storms.

exhaust gas is the same as the density of air at the temperature and pressure of the exhaust.In Equation A9, (Fso2)in is the number of moles of SO2 entering the catalyst per hour
