The Smoke, Clouds and Radiation - Brazil (SCAR-B) Project was conducted in Central Brazil and southern Amazon Basin from August 15 to September 20, 1995. This describes the Brazilian meteorological contribution to SCAR-B mission, including the occurred climate study and the weather analysis and forecast. Twice daily forecast, based on Centro de Previsão de Tempo e Estudos Climáticos and National Centers for Environmental Prediction (NCEP) model outputs and conventional observations, provided special support for mission plans. Long periods of haze, low index of relative humidity and also little cloudiness and rain occured during the mission due to frontal system's blocking at South Pacific Ocean. Backward trajetory calculations show three types of air particles which have come from Pacific Ocean, Amazonia and other continental regions. Some results demonstrate the strong sensitivity of the atmosphere-surface radiative budget to the optical parameters of smoke particles at Cuiaba site.
