Problem Definition: In order to account for the chemistry occurring in the rocket plume before it gets diluted into the large-scale climate model grid-cell, parameterizations need to be developed and used in global models. Such a plume parameterization will be developed in LMDZ-INCA for further use by the other global models.
Research Objectives:
- Development of a new global model version including the emission of pollutants from rocket launches and impact on gas phase ozone chemistry
- Consider the chemistry in the plume exhaust before dilution in the global model
- Include the aluminium cycle in the model and the perturbations associated with rocket launches and space debris
- Consider different emission inventories to account for various types of fleet, emissions, fuel types and geographical distributions
Expected Results:
- Ability to simulate the impact of rocket launches and space debris on atmospheric composition in LMDZ-INCA model
- Quantification of the impact of various fleet scenarios of rocket launches on atmospheric composition and climate
- Improved representation of plume processes and aluminium chemistry in the global atmospheric model
Secondments:
- University of Leeds (UL, Leeds, United Kingdom, ca. 5 months): alumina chemistry and microphysics scheme
- Finnish Meteorological Institute (FMI, Helsinki, Finland, ca. 3 months): development of a sub-grid plume processing scheme for global models
