What's new in the latest release?
The current CHIMERE version is chimere2014b.
This is mainly bug a fix release but
also includes computation speed optimization of the Boundary Conditions pre-processor. Due to important bug fixes in chimere2014a all the users are strongly encouraged to upgrade to chimere2014b.
New in chimere2014:
- Added the FastJ radiative transfer model to compute photolysis reaction rates. This makes it possible
to extend the model domain vertically beyond 500 hPa. An automatic calculation of optical depth (for
clouds and aerosols) is also done.
- Added possible read of fires emissions fluxes (if provided by the user)
- Added SAPRC-07-A chemical mechanism
- Updated ISOROPIA V2006
For more detail see the CHIMERE Documentation (in PDF).
- Activated adaptive CFL condition. This speeds up computations.
- Improved deep convection calculation. This speeds up computations and yields more realistic ozone land-sea interfaces.
- Diagnostics of meteorological parameters, mineral dust and biogenic emissions are calculated on-line in the model core.
- Improved calculations of boundary conditions (with new datasets built with LMDz-INCA, GOCART and MACC global climatologies)
- Optimized calculations of vertical levels
Short model description
The CHIMERE multi-scale model is primarily designed to produce daily forecasts of ozone, aerosols and other pollutants and
make long-term simulations (entire seasons or years) for emission control scenarios. CHIMERE runs over a range of spatial scale from the regional scale
(several thousand kilometers) to the urban scale (100-200 Km) with resolutions from 1-2 Km to 100 Km. On this server,
documentation and source codes are proposed for the complete multi-scale model. CHIMERE proposes many different options for simulations which make it also a powerful research tool for testing
parameterizations, hypotheses. CHIMERE is a parallel model that has been tested on machines ranging from desktop PCs running the GNU/Linux operating system, to massively
parallel supercomputers (HPCD at ECMWF).
