- Abstract:
- Human activities are causing changes to the Earth's atmosphere. Release of long-lived pollutants such as CFCs have depleted the ozone layer. Increases in various pollutants (e.g. NOx, CO, hydrocarbons) have decreased air quality in the lower atmosphere. Increases in greenhouse gases (GHGs), such as CO2, have caused the lower atmosphere to warm and the stratosphere to cool. All of these changes are interlinked and understanding their current and future impact requires sophisticated atmospheric models. Climate models are used to predict the future meteorology of the atmosphere. However, these models are expensive to run and generally do not include detailed chemistry. Even those that do tend to be either just stratospheric (for looking at changes to the ozone layer) or tropospheric (for studying changes to air quality). In this proposal we will combine two established codes for calculating atmospheric chemistry to produce a combined chemistry-climate model able to simulate the chemistry of the whole lower-middle atmosphere in a detailed way. We will use this model to study key areas of scientific importance. We will investigate if the continued use and emission of short-lived brominated (or chlorinated) compounds could continue the depletion of the ozone layer despite international agreements to ban long-lived pollutants. We will investigate how changes in the lower stratosphere may effect the future air quality of the lower atmosphere - past studies with simpler models have shown conflicting results. Finally we will use the model to predict how the composition of the atmosphere will evolve over the next century under different assumptions of GHG emissions and identify the key ways in which climate change may affect air quality.
