Atmospheric Chemistry

This research subject is related to the modelling of atmospheric species or aerosols like secondary organic aerosols in global climate models, with an specific interest in ozone and heterogeneous chemistry. My experience in atmospheric chemistry has two different aspects: the analysis of the simulations of global climate models with interactive chemistry in the framework of CCMI and AerChemMIP, and the development/improvement of chemistry schemes in climate models. In the last aspect, I participated in adding new species to the tropospheric chemistry module of IPSL climate model, in particular substances like glyoxal, hyac, glyald between others in the gas-phase with the idea of improve also the *aqueous phase* and heterogeneous chemistry reactions where these species have an specific role.
The topic of atmospheric chemistry has been part of the previous projects briefly described below (CMIP6, AerChemMIP) and current projects: CLIMDO:

Collaboration in external projects

  • AerChemMIP: rather than an specific project it is a intermodel comparison in the umbrella of CMIP6 (an specific MIP) designed to quantify the climate and air quality impacts of aerosols and chemically-reactive gases in the climate models that are used to simulate past and future climate. Publications: Thornhill et al. (2021) Thornhill et al. (2021)
  • CMIP Phase 6 (CMIP6): The paper Keeble et al. (2021) analyses the stratospheric ozone in the context of CMIP6 models (both main deck and AerChemMIP). Previously, the publication Checa-Garcia et al. (2018) detailed the radiative forcing of the historical CMIP6 ozone forcing dataset both in the stratosphere and the troposphere.
  • CLIMDO, this project evaluates the several chemistry processes in the modelling of mineral dust. Therefore, it comprises both: experimental measurements of chemical processes and the modelling of these processes in a global climate model with interactive chemistry.
