CPTEC stands for 'Centro de Previsão de Tempo e Estudos Climáticos' and INPE for 'Instituto Nacional de Pesquisas Espaciais'. CPTEC is the most advanced numerical weather and climate forecasting center in Latin America, with high-precision short and medium-term weather forecasting since the beginning of 1995. See http://www.cptec.inpe.br/ for more information.
