The objective of this study was to develop software using artificial neural networks (ANNs) for the estimation of air temperature in the Northeastern region in Brazil. The architectures, the activation functions of the artificial neurons and the free parameters of the ANNs were defined to build a mathematical function to represent the ANN. The mathematical function was implemented by using Borland Delphi© 7 with a graphic interface to facilitate the use of the software. The software developed was denominated netTemperatura NE. It allows making a quick and easy estimation of the minimum, mean and maximum air temperatures (monthly or annual) in the Northeastern region of Brazil as a function of geographical coordinates and surface elevation.
