| Abstract: | We compute the input of meteoric materials expected on Titan, and integrate this dust model with an ablation model and a comprehensive chemical model, investigating the effects on the atmosphere and surface. We find that a water deposition of 10-100 times the expected interplanetary dust flux /7/, or a recent large impact, is required to produce the observed CO2 abundance /2/. Ionisation due to meteoric activity is not likely to be higher than that due to other sources. |
