Model description
Modelling of spatially and temporally resolved CO2 concentrations is realized with the modelling system COSMO-GHG. COSMO stands for Consortium for Small-Scale Modelling and is the operational weather forecast model used by MeteoSwiss. The extension of a greenhouse gas (GHG) module has been developed by Empa and is directly coupled to the latest version of COSMO. The model allows simulating the emissions and transport of CO2 (and other greenhouse gases) for whole Switzerland.
Example simulation
COSMO-GHG simulation of total CO2 concentration (left panel), biospheric component (top right) and from anthropogenic sources (bottom right). All fields are at the lowest model layer. Simulation time period is March 2019. After a stormy period in the first half of March, a high pressure system dominated during the second half. This also becomes apparent in the concentration levels of CO2. Software used for video: Python and ffmpeg. |
