BRAMS (Brazilian Regional Atmospheric Modeling System) is a joint project of ATMET, IME/USP, IAG/USP and CPTEC/INPE, funded by FINEP (Brazilian Funding Agency), aimed to produce a new version of RAMS tailored to the tropics. The main objective is to provide a single model to Brazilian Regional Weather Centers. The BRAMS/RAMS model is a multipurpose, numerical prediction model designed to simulate atmospheric circulations spanning in scale from hemispheric scales down to large eddy simulations (LES) of the planetary boundary layer.

BRAMS Version 4.0 is BRAMS Version 3.2 plus: Enhanced Portability and Software Quality (new procedure to read RAMSIN, corrections needed by others compilators, new scheme to build executable code, etc). Improved serial and parallel performance (best vectorization in same codes, improvements on performance for advection scheme and improvements in master slave comunications). Inclusion of TEB (Town Energy Budget) and SPM (Simplified Photochemical Model) scheme. Inclusion of CATT (Coupled Aerosol and Tracer Transport) scheme. Corrections in Shaved ETA scheme based on RAMS 6.x. Corrections in LEAF scheme based on RAMS 6.x.
