This is the portal for the TM5-zoom model, i.e. the original TM5 model. For TM5-MP, where chemistry is further developed, go to the TM5-MP portal.

The TM5-zoom model simulates transport & chemistry of atmospheric tracer(s). Zooming consists in 2-way nested regions. 4D-variational data-assimilation built upon TM5-zoom is possible. It is based on the adjoint of the transport code (including zoom), and is hosted elsewhere (see the homepage for further details).
