Model CPTEC / INPE gains new functionality: simulation of the carbon cycle


The CCATT – BRAMS system for environmental and integrated modeling of the Center for Weather Forecasting and Climate Studies (CPTEC) of the National Institute for Space Research (INPE), now has the carbon cycle and other biogeochemical cycles among its features.

Include the simulation of the carbon cycle was possible from the defense of the doctoral thesis of Demerval Moreira , on the last day 17 , the Graduate Program in Meteorology INPE. Guided by researchers Saul R. Freitas and Jose P. Bonatti , the development of the thesis resulted in a new system that represents the state – of-the- art regional modeling of the atmosphere including chemical processes , aerosols and fully coupled biogeochemical cycles.

Streams containing gases (CO2 , CH4, CO) and other gases (for example , volatile organic compounds) , in addition to energy, time and water are simulated by the model surface Joint UK Land Environment Simulator (Jules ) coupled to CCATT – BRAMS . The collaboration with British researchers within the Amazon / NERC project gave the system JULES – CCATT – BRAMS ( initial results were published in the article Moreira et al. (2013).

JULES The scheme also provided significant performance gain in forecasting time with BRAMS being used operationally since a year ago at CPTEC / INPE forecast time scale quasi- convective ( .

The new version of BRAMS (v 5.0 ) with sub – models and JULES CCATT (chemistry and aerosols ) will be released and distributed freely to the scientific community in July 2014.
