Numerical models

LISA develops and/or uses digital tools to model spectra, reverse satellite observations data, to study chemical processes, quantify dust emissions, or even to perform atmospheric modeling coupling emissions, transport, chemistry and deposition.

 

Modeling and simulation of Spectra

Objective : calculate the energy levels, intensities and profiles of molecular lines

 

Inversion of the IASI data

Objective : Reverse infrared spectra fromsatellite IASI to determine concentration profiles or integrated chemical species content

 

Explicit generation
of chemical schemes

Objective : describe explicitly the oxidation multiphasic of volatile organic compounds (VOCs) in the atmosphere

 

 

Modeling of dust emissions

 Objective : quantify emissions of desert aerosols by describing their spatial and temporal variability

Chemistry-transport models

Objective : Analyze and forecast fields of concentrations of chemical and particulate species
