Droughts are complex natural phenomena that influence society's development in different
aspects; therefore, monitoring their behavior and future trends is a useful task to assist the
management of natural resources. In addition, the use of satellite-estimated rainfall data
emerges as a promising tool to monitor these phenomena in large spatial domains. The
Tropical Rainfall Measuring Mission (TRMM) products have been validated in several
studies and stand out among the available products. Therefore, this work seeks to evaluate�…

Drought is a natural phenomenon that originates from the absence of precipitation over a
certain period and is capable of causing damage to societal development. With the advent of
orbital remote sensing, rainfall estimates from satellites have appeared as viable
alternatives to monitor natural hazards in ungauged basins and complex areas of the world;
however, the accuracies of these orbital products still need to be verified. Thus, this work
aims to evaluate the performance of Tropical Rainfall Measuring Mission (TRMM) satellite�…
