The present work applies the model of Rey to calculate the potential vegetation of the Northeast of Brazil and, thus, to verify if it properly identifies the biomes of that region. The method used to calculate the rate of Evapotranspiration (ET) is based on the equation of Penman-Monteith. The model also includes fixed parameters and the variables vegetation height and leaf area index (LAI). In general, the model provided a good representation of the biomes of the Northeast of Brazil, mainly the Caatinga, the Cerrado, and the Atlantic Forest.
