英文摘要	The Northeast of Brazil is characterized by a semi-arid climate and irregular rainfall over time, which jeopardize agriculture production, public supply and other sectors. In this sense, research activities that promote Sustainable Development provide subsidies for the implementation of new public policies aimed at water sustainability in the region. The purpose of the present research was to compare rainfall data obtained from pluviometric stations of the Fundacion Cearense de Metrologia y Recursos Hidricos (FUNCEME) (translated as Cearense Foundation of Meteorology and Water Resources), with precipitation estimates obtained by means of the Tropical Rainfall Measuring Mission (TRMM) satellite, from January 1, 1998 to December 31, 2017, totaling twenty years of analysis for the entire state of Ceara, Brazil. In its first part, the research employed the techniques of comparing pixel to point (A and B), point to pixel (C), and pixel to pixel (D) along with inverse distance weighted (IDW) interpolation; in the second stage, data were analyzed by accuracy evaluation metrics: mean absolute error (MAE), root- mean-square error (RMSE) and the correlation coefficient (r). Analyzes results indicated TRMM satellite imagery to be a good alternative with 16.46 mm MAE, 26.78 mm RMSE and a correlation coefficient of 0.96.
