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. The newest release is BRAMS Version 4.2.

BRAMS Version 3.2 is RAMS Version 5.04 plus: Shallow Cumulus and New Deep Convection (mass flux scheme with several closures, based on Grell et al., 2002). Binary reproducibility (same results independent of processors) New 1 km vegetation data derived from IGBP 2.0 + IBGE/INPE dataset LEAF-3 with observed parameters for South American biomes Enhanced Portability and Software Quality Heterogeneous Soil Moisture assimilation procedure Operational assimilation cycle and Forecast procedure SIB2 surface parameterization Improve serial and parallel performance
