The book Models for Estimating Solar Radiation and Evapotranspiration discusses the importance of knowing some models for calculating solar radiation from air temperature and their influence on obtaining reference evapotranspiration. It is therefore an up-to-date book, with an important contribution from the author in the interpretations, discussions and opinions of the subjects covered, presented in a fluent and easy-to-read manner. However, the reader's familiarisation with meteorology/climatology and related knowledge will make the reading more fruitful. The publication has its place, filling the gap that still exists as a source of subjects that are still little explored today. It should therefore serve as a source of reference for post-graduate students, technicians, teachers and researchers.
